The Mark VI Circuit-Switcher offers the latest in interrupter technology. It features a 31.5-kA fault-interrupting rating and 3-cycle interrupting time with simultaneity of less than ¼ cycle. No shunt-trip device is needed. The Mark VI Circuit-Switcher is significantly lighter than the Mark V Circuit-Switcher, is easier to install, and has reduced maintenance requirements.

The Mark VI Circuit-Switcher uses the same rugged integral disconnect as the Mark V, making it perfect for use with pre-insertion inductors.
