Blue Sea 7258 100A C-Series Double Pole Breaker

The Blue Sea 7258 C-Series Toggle Circuit Breaker meets 5,000 amp interrupt capacity requirements for 120/240 volt main protection per ABYC, at 100A. It is designed for boaters wiring a higher-amperage 120/240V AC main who need a breaker that works as either a double-pole 120V main or a triple-pole 240V main.

Used as a double pole breaker, it switches hot to neutral for a 120V AC main; used as a triple pole breaker, it switches both lines (hot) and neutral for a 240V AC main. All poles trip together if any single pole trips, and the trip-free design means it can't be held ON during a fault current condition.
