AC & DC switches for on load, off load and off load – fault make applications.

Refer to the Switch Finder Table below.

These can be manually operated or automated by Electric drive or Pneumatic drive. Switches of multi pole construction are available typically up to 6 poles for off load switches.

The configurations can be typically:

· Disconnectors (1-0)

· Changeover (1-2)

· Changeover Disconnectors (1-0-2)

Many options are available including;

· Interlocking

· Multiple Auxiliary indication

· Padlock facilities
