Construction characteristics
From the inside out, safety is of paramount importance with
2
special attention given to live parts insulation and segregation between phases. Careful selection of materials, meticulous assembly, rigorous testing, and unsurpassed experience make
1
Magnum a proven reliable product.
1
Rigid frame housing
1
Magnum circuit breakers use a rigid frame housing construction
1
of durable engineered thermoset composite resins.

Strong and lightweight material with strength to weight ratio twice that of steel. Proven able to withstand high dynamic and thermal stresses.
•
Excellent dielectric characteristics, resisting arc tracking.
Three piece construction
The 3-piece construction (rear housing, front housing, and cover) provides support while isolating and insulating power conductors
•
A 2-piece case encloses current paths and arc chambers. Chambers act to channel arc gases up and out during interruption.
•
The operating mechanism and accessories sit on the front of the case. Only the insulating front cover needs to be removed to access mechanism and/or accessories .
•
The operating mechanism achieves a longer life as a result of reduced frame deflection during operation along with stiff component mounting.
Two-step stored energy mechanism
Magnum circuit breakers are equipped with a true 2-step stored energy mechanism.
•
Closing springs can be charged manually or electrically.
•
5 to 7 downward strokes on the charging handle completes charging process.
•
Mechanism provides for a complete OPEN – CLOSE – OPEN cycle.
Unsurpassed performance design
The performance characteristics of the Magnum breaker are attributed in many ways to a C-loop current path design and movement. Contact fingers perform both the main and arcing contact functions on different parts of the same finger. A complete movable contact assembly is a combination of a number of single contact fingers. The exact number of contact fingers required depends upon the frame size and interrupting rating of the breaker. Braided connectors (flexible shunts) are used to attach each contact finger. The result is an efficient and uniquely functional main contact system with the following advantages:
•
Eliminate bolted joints reducing hot spots.
•
Reduced mounting space for primary contacts.
•
Smaller and lighter operating mechanism for longer life.
•
Higher interrupting and short time (withstand) ratings.
•
5-cycle or less closing.
•
Improved contact material.
•
Contact wear indicator for each primary contact structure.
•
Individually removable arc chambers insulate/isolate each pole.
•
Able to withstand high dynamic and thermal stresses.
Value added features
Magnum provides numerous other internal and external features that further enhance the reliability, maintenance and safety of this industry leading product offering. A number of additional common features are highlighted below. See Section 7 for trip units, and Section 8 for accessories, for more in-depth information.
•
Available Arcflash Reduction Maintenance System™ on Digitrip 520MC and 1150, to lower personnel risk and PPE levels in the arcflash boundary.
•
Field installable trip units, sensors and accessories.
•
Mechanical and electrical anti-pump features.
•
Easily removable arc chutes for inspection.
•
Common accessories for all frame sizes (electrical and mechanical).
•
Automatic drawout primary shutters.
•
Conveniently located finger proof secondary contacts.
•
Will accommodate a variety of primary terminal types/ configurations.
Breaker mounting configurations
Most Magnum circuit breakers are available in both fixed and drawout configurations. In a small number of instances, however, only a fixed configuration is available.
Fixed mounted breakers
All Magnum circuit breakers, except for the MDSL breaker, can be fixed mounted. The breaker bolts directly to the enclosure main bus, which allows for efficient current transfer under loaded conditions. Metal mounting feet are provided as a standard feature for use in securely bolting the breaker to the enclosure. Fixed circuit breaker construction is simple and economic because there are no drawout system components.
A fixed circuit breaker is supplied with horizontal, pre-drilled primary terminal pads for terminating the breaker to the bus.
ote:N Optional vertical primary adapters are available to accommodate
different bus configurations. See Section 11 for a complete overview of detailed dimensions.

Drawout mounting
A drawout circuit breaker is used in combination with a cassette. The cassette provides for all the required drawout features for both primary and secondary connections. Mounting locations for cassette mounted cell switches, primary safety shutters and various key interlocks are part of the cassette design, to allow for customized customer options. Refer to Section 11 for specific drawout circuit breaker and cassette dimensions.
Cassettes – Available styles
Narrow frame Cassettes (for narrow frame and double narrow frame breakers)
For narrow frame circuit breakers, there is one type of cassette design, which uses horizontal stabs. Horizontal customer busbar terminals are available (sold separately). Optional bolt-on 90 -degree adapters can be used to rotate the cassette’s primary terminals to a vertical orientation as required.
Standard frame Cassettes (for standard frame and double standard frame breakers)
For standard and double frame circuit breakers, there are three cassette styles, all with vertical stabs available:
•
Basic Cassette with copper stabs - This cassette comes with factory installed copper stab/terminals on the cassette.
•
Basic Cassette without copper stabs - The basic cassette can also be ordered without factory supplied copper stab/ terminals. Ordering without stabs allows the switchgear builder to integrate the cassette by using their vertical busbars.

Magnum DS - Current limiting circuit breakers
MDSL circuit breaker
Magnum MDSL current limiting power circuit breakers utilize integral current limiters to provide interruption ratings of 200 kA at 600 Vac with continuous limitation with lower let through currents for superior protection of downstream equipment. The MDSL breaker is available only in a drawout configuration.
Current limiters are held in place in a 6 inch (152.4 mm) extension provided on the back of the circuit breaker. The current limiters can only be removed from the breaker and replaced when the MDSL breaker is removed from its associated compartment.
A blown limiter indicator provides a visual indication on the front of the MDSL when a current limiter in any phase has interrupted a short circuit. The indicator itself is a red pop-out button located on the lower left portion of the breaker’s front cover. The direct trip actuator trips the circuit breaker, and an output to the indicator causes the button to pop out.
Current limiter selection
Current limiters can be selected from the current limiter selection table (Table 7) and are categorized for selection in three ways:
•
Minimum current limiter
•
Recommended current limiter
•
Maximum current limiter
The selection of a suitable limiter rating for a given application is generally governed by a choice of the following two types of protection:
(A) Maximum protection of downstream components:
Type MDSL breakers are often used for this purpose even when the maximum available fault currents are within the interruption rating of the corresponding unfused Magnum breakers.
(B) Protection of circuit breaker only:
Case A would tend to use the smallest available limiter; Case B the largest.

Select the current limiter based on the Magnum breaker frame and current sensor and rating plug as shown.
2
Refer to MDSL current limiter curves for let-through and time characteristics.
3
The recommended ratings provide for reduced current let-through and breaker coordination within the trip unit settings. Selection of current limiters below the recommended ratings shown provides lower current let-through, however, trip unit settings must be considered to avoid nuisance operation.

MAGNUM PRODUCT GUIDE CA013002EN—April 2017 www.eaton.com24
A non-automatic power circuit breaker includes separable contacts for movement between a closed position and an open position, and an operating mechanism for moving the separable contacts between the two positions. This breaker can be applied where a local means of disconnect or isolation is required. It can be operated either manually or electrically. It should be noted, since the Magnum Non-Automatic Breaker (switch) does not include any overcurrent protection, it cannot be used in branch or feeder circuit protection applications.
MDE circuit breaker
The Magnum DS Family includes the MDE High Endurance Circuit Breaker. The MDE circuit breaker is rated for 15,000 Open-Close operating cycles between scheduled maintenance periods. It is a specially designed and manufactured Magnum DS Circuit Breaker intended for especially robust applications that require a higher than normal number of operating cycles without maintenance.

Magnum SB circuit breaker details
Magnum SB is a low voltage insulated- case circuit breaker family designed for the performance requirements of UL 891 switchboards. These characteristics are:
•
Magnum SB breakers have short time current ratings and fixed internal instantaneous trip ratings, which is characteristic of UL 489 molded-case breakers commonly used in UL 891 switchboards. This provides for improved coordination and selectivity for most commercial switchboard applications.
The instantaneous trip function facilitates feeder circuit breaker protection in UL 891 switchboards with 3-cycle bus bracing. This yields reduced energy let through to downstream circuits by eliminating the fault current above the fixed instantaneous trip point.
•
Magnum SB insulated- case circuit breakers have Interruption ratings up to 150 kA with continuous current ratings up to 5000A.
Magnum SB non-automatic breaker (switch)
The non-automatic Magnum SB breaker (switch) shares the same frame and accessories as the circuit breaker. It does not, however, have the following:
•
Trip unit
•
Sensors
•
Overcurrent release
Like the Magnum SB breaker, the switch is available in both three-pole and four-pole, fixed and drawout configurations.
A non-automatic circuit breaker includes separable contacts for movement between a closed position and an open position, and an operating mechanism for moving the separable contacts between the two positions. It cannot be used for branch- circuit protection.

Catalog number selection
Just like the Magnum DS, the Magnum SB circuit breaker is defined & ordered by a 25 character catalog number created through a simple selection process from two configuration tables. If the breaker is a drawout breaker, the associated cassette would be defined by a 15 character catalog number. The cassette selection process is similar to that of the circuit breaker.
ote:N The selection examples shown at the top of each table, and that all
combinations are not possible.

These interruption ratings are based on the standard duty cycle consisting of an open operation, a 15 second interval and a close-open operation, in succession, with delayed tripping in case of short-delay devices. The standard duty cycle for short time ratings consists of maintaining the rated current for two periods of 1/2 seconds each, with a 15 second interval of zero current between the two periods.
