Versatility
ABB disconnect switches are designed to offer maximum versatility in many ways.
Broad range
ABB's open style non-fusible switches have seventeen amperage sizes from 16–2000 A
The fusible range is 30-1200 A. All sizes are compact, heavy duty, 600V, disconnect switches.
Many sizes are available in 2, 3, 4, 6, and 8 pole configurations.
ABB’s offer also includes non-fusible DC switches from 16-600 A specifically designed for
solar applications, heavy duty safety switches (30-1200 A) and general duty enclosed
switches, both fusible fusible (30-800 A) and non-fusible (16-2000 A).
Compact size
The non-fusible disconnect switches' compact dimensions allow panel size reduction in
new applications or easily retrofit into space-sensitive existing installations. The fusible
disconnect occupies only little more panel space than the appropriate fuses.

Installation options
Rotary through the door: available in all sizes, non-fusible 16-2000 A;
Flange: versions available in 30-1200 A sizes.
A rotary disconnect may be installed nearly anywhere in a control panel — mounting is not
limited to the upper right hand corner of the panel.
Mount the disconnect where it conveniently fits in your panel and simply install the handle
on the door, in line with the disconnect. The disconnect and handle are mechanically
linked through an easily adjusted shaft. This allows fast and easy installation into panels of
different depths and layouts.

General information
Mounting
Disconnect switches offer several mounting possibilities:
Door mounting on an enclosure door or sidewall for non-fusible, 16 - 100 A
•
• DIN rail mounting for non-fusible, 16 - 200
A; and fusible, 30 - 100 A
• Base mounting with screws for all disconnect sizes
• Adjustable mounting feet for non-fusible, 200 - 1200 A, and fusible 60 -1200 A
Mounting positions
Disconnect switches offer several mounting possibilities:
Terminal connections
Versatile connecting possibilities for non-fusible and fusible switches
• Ring tongue crimp on lugs
• Direct bus
• Terminal lugs
Finger proof
Dead-front construction plus terminal shrouds reduce the risk of touching live
parts, improving safety and reliability of the instalation
Incoming power feed
Disconnect switches can be used equally well with either top or bottom
incoming power feed.

Revised January 2015
General information
Modular construction
Different pole configurations make it easy to install the disconnect inside the enclosures
as well as enhance the external operation through the pistol handles.
Door interlock
The handle and shaft provide a door interlock; the door cannot be opened when the
switch is in the “ON” position. NOTE: Some handles provide a method for qualified personnel to circumvent the door interlock. This is commonly referred to as a “defeater” mechanism.
19
Padlockable
Handles can be padlocked in the “OFF” position with up to three padlocks. Additionally - with a direct mount handle - the switch mechanism can be directly padlocked in
the “OFF” position when the door is open. NOTE: Some handles can be ordered with
the ability to padlock in both the “ON” & “OFF” positions, please consult your ABB
sales office.
Positive opening operation
All switches operate according to the “positive opening operation” principle. This means the
contacts are opened and closed by a driven mechanism, a solid moving bridge, not merely
springs. This provides reliable position indication to the user; if the disconnect is in the
“OFF” position, the contacts are open.

45°
Max
Welded contact protection
Positive opening operation safeguards users in case of welded contacts causedby
an overload or short circuit. The handle cannot reach the “OFF” position unless the
contacts are truly open. If any or all of the contacts are welded shut, the disconnect
mechanism will only allow the handle to operate a maximum of 45°. This safeguards
personnel by:
• Alerting them a problem has occurred
• Maintaining the door interlock and
• Not allowing a padlock to be inserted
Clear position indication
All disconnects and handles have clear “ON” and “OFF” designations.
Whether the door is open or closed, it is possible to simply look at the
disconnect and determine if it is “ON” or “OFF”.
Visible blades
Visible blades offer additional safety for non-fusible switches, 200 - 1200 A
Track resistant material
Excellent track resistant material reduces the risk of flash-over between phases
in even the most severe circumstances.
Constant control for non-fusible disconnect switches
The OT16 to OT100 provide the user with constant control over the power circuit.
Whether the enclosure door is open or closed, qualified personnel have the ability to manually operate the disconnect. This is most meaningful when qualified personnel are
working with the enclosure door open: In case of an emergency down-stream, the main
three phase power can be disconnected immediately using the black, direct mounted
handle.

General information
High performance
The
mechanism is quick-make/quick-break, meaning the contacts operate independently
of the speed and force at which the handle is operated. This, in combination with unique,
patented self-cleaning contacts, provides a long, reliable, electrical life.
Superior short circuit protection
Fuses efficiently limit the peak let-through current, i2t, during a fault better than any other
product, contributing to safety and reliability. Selectivity and coordination are easily accom-
plished with fused protection. Fusible disconnect switches accept a wide range of fuses:
Class CC 30A
Class J 30 – 600 A
Class L 800 – 1200 A
Fuse isolation
Fused switches have contacts on both sides of the fuse. The fuses are totally isolated in
the “OFF” position, reducing the risk of electric shock to authorized personnel — even if
the disconnect is being back fed.

Flange operated fusible and non-fusible disconnect switches
ABB’s solutions comply with NFPA79 requirements for Flange Operated Fusible and Non-fusible Disconnect Switches.
NFPA 79 requires main disconnecting means to be operable without the use of accessory tools or devices, independent of door
position. This code also includes an interlocking provision to prevent the closing of disconnects while the enclosure door is open,
unless an interlock is operated by a deliberate action.
The flange operated disconnect switches are available as ridged shaft or flexible cable operated versions. The cable operated
version allows you to install the disconnect switch virtually anywhere in the enclosure depending on the length of the cable.
Cables are available in lengths up to 84 inches.
The designs are cost-effective NFPA 79 solutions offering quick and easy installation.
For disconnects above 100 A
Rotate the OT_03 disconnect 180 degrees to mount on the operating mechanism
Operating mechanism required for OT30-200. Not required for OT400-1200 (included)
