Mark V Circuit-Switchers are especially suited for switching and protection of shunt capacitor banks. They can be fitted with optional pre-insertion inductors to minimize capacitor-bank switching transients, markedly improving power quality.

The Mark V Circuit-Switcher uses an in-series circuit-breaking interrupter and a circuit-making and isolating disconnect, making it especially suited for switching and protection of transformers, lines, cables, capacitor banks, and line-connected or tertiary-connected shunt reactors. The Mark V Circuit-Switcher is available in three styles — Vertical-Break, Center-Break, and Integer.
