2. Compact welded-steel tank protects switching and protection components from the environment.
3. Gang-operated three-pole fault interrupters — individually operated single-pole fault interrupters are also available.
4. Pressure gauge (under window) is temperature and altitude compensated
5. Operating mechanisms for switches and fault interrupters are padlockable in any position.
6. Operation selector prevents inadvertent operation from closed position directly to ground, and vice versa.
7. Programmable overcurrent control
8. Large viewing windows allow operator to see the open gaps and ground positions of the switches and fault interrupters.
