50 A Single-Pole DC Circuit Breaker

A single-pole series 63 DC breaker, 50 amps at 250 volts DC, certified CB, CE, TUV, RoHS to IEC/EN 60947-2.

One standard DIN-pitch module protecting a board feeder or the link between a charge controller and its bank. The 50 A rating matches the output of a mid-size MPPT controller on a 12 or 24 volt bank.

Like every single-pole unit in the series it breaks one conductor only: fine on the battery side, where the negative is usually common, but not on a floating string where both poles must be isolated together. Respect the connection direction marked on the housing.
