Compact Switches
February 1st 2006

ABB has extended its range of compact switches as part of its ongoing replacement programme for the OETL and OESA ranges. Up to 48% smaller, the OS and OT switches are suitable for applications where time, cost and space are at a premium.

OT switch disconnectors and OS fuse switch disconnectors can be used as the main switch in low voltage switchgear for power distribution, starting and stopping of motors and isolating loads during maintenance.

Available in metal or plastic enclosures, they can be used as safety switches to prevent accidental starting of machines.

The external operating handles have been doubleinsulated, which eliminates the chance of touching live parts. The fuse covers cannot be opened when the switch fuse is on.

Further safety is provided by arc-chutes, which prevent current sparks and flashovers.

The OS range provides coverage from 16 to 400A; the OESA provides to 800A.
