The most compact disconnect (isolation) solution

Optimally designed, the OT disconnect switch offers an
advanced and compact solution, providing you with added
value.

• The new double-sided spring construction in
combination with fewer components made an
innovative and compact design of the operation
mechanism possible.

• The uniquely short current path enabled a small-sized
contact construction.

High performance despite
the small size

The powerful new construction, with its
quick-make and quick-break operation
features and two contact points instead
of one, adds value to and enhances the
performance of the disconnect switches.

• The OT range offers you improved power
ratings, the highest on the market. Full I
ratings can be used both in open air and
in enclosures, without having to derate or
enlarge the box.

• User-friendly and flexible, the OT disconnect
switch provides you with full horse power
ratings for all the voltages, even up to 600 V.

The OT disconnect switch is easy to
use and a snap to install according to your
choice: horizontally or vertically - even in the
ceiling! The adjustable mounting feet allow
both top and side mounting of the switch.

ABB’s disconnect switch range meets
disconnect and isolation requirements more
effectively than ever, maximizing the benefits
and optimizing your use of assets.
