ABB SACE Emax 2 Technical Catalog

Distinctive features

Performance

The SACE Emax 2 for UL 1066 range is made up of 4 sizes: E1.2, E2.2, E4.2 and E6.2 up to 6000A1), which enable switchgear of compact dimensions and high ratings to be built with busbars of reduced length and cross-section. The protection trip units, auxiliary connections and main accessories are the same throughout the range to simplify design and installation. Furthermore, the sizes from E2.2 to E6.2 have the same height and depth. The rating levels are updated and uniform throughout the sizes to meet the demands and needs of today’s installations, from 42kA to 150kA at 508V and to standardize switchgear projects. High short-time withstand currents, together with the efficiency of the protection functions, guarantee complete selectivity in all situations. Accurate design and choice of materials enable optimization of the overall dimensions of the circuit breaker. In this way switchgear of compact dimensions can be built and outstanding savings at the same performance can be obtained.

In particular: – E1.2 offers 1200A with an interrupting rating of up to 65kA and a short-time withstand current of 50kA in an extremely

compact structure. In the three and four pole version, it offers the sturdiness of SACE Emax with reduced dimensions and enables switchgear of 65kA to be built in units of 16 inches, which is indispensable in places where reduced dimensions are essential, such as naval and offshore installations.

– E2.2 enables ratings of up to 2000A to be achieved in switchgear with a width of 16 inches when the three pole version is

used. In addition, it provides an interrupting rating of up to 100kA and withstand current of up to 85kA.

– E4.2 is the new standard for circuit breakers up to 3200A. It is designed for interrupting ratings up to 100kA at 508V and

short-time withstand currents of up to 100kA without the need for particular precautions.

– E6.2 is the top of the range, with an interrupting rating of 100kA, a withstand rating of up to 100kA and a structure that

allows 6000A

to be reached, even in complex installation conditions.

SACE Emax 2 switch disconnectors IEC 60947

Switch disconnectors, identified with the abbreviation “/MS”, are devices that satisfy the isolating specifications provided by the IEC 60947-3 Standard. The switch disconnectors are derived from the corresponding automatic circuit breakers, and they have the same dimensions and accessory options. This version differs from the automatic circuit breakers only because of the absence of protection trip units.

The device, when in the open position, guarantees an isolating distance between the main contacts of the circuit breaker that is sufficient to ensure that the installation downstream is not live. Furthermore the switch disconnectors, if used with an external protection relay with maximum delay of 500ms, enable a breaking capacity at a maximum rated operating voltage (Ue) equal to the value of rated short-time withstand current (Icw) for one second.

Protection trip units

Architecture

All SACE Emax 2 circuit breakers are equipped with protection trip units that are interchangeable from the front with just a few, simple operations by the customer. There is no need to dismantle the circuit breaker or access any internal or sensitive parts.

This enables personalization of the functions available, even during commissioning or when the circuit breaker has already been installed. In particular, SACE Ekip consists of: – Protection trip unit, available with different interfaces and versions that range from basic to more complete; it contains a

latest generation microprocessor that performs all the functions of protection and control.

– Ekip Measuring Module, connected internally to Emax 2, performs voltage, power and energy measurements with high

accuracy without requiring any external connection or voltage transformer. The Ekip Measuring Pro version also performs all protection functions based on voltage and power without the need for external units, thereby simplifying design and construction of the system.

– Interchangeable rating plug enables all protection thresholds to be adjusted according to the rated current, increasing

flexibility for the customer. It is useful in installations that are prepared for future development or in cases in which the power supplied may be limited temporarily.

– Main board is the mechanical housing of the trip unit, which includes a micro-controller for measuring currents and the

self-protection functions. The separation of main board and protection trip unit ensures excellent reliability and immunity to conducted and radiated emissions. Integrated new generation Rogowski sensors, which are sensitive to the true r.m.s. value of the current, guarantee high accuracy of both measurements and protection.
