The w58xc4c12a10 is a TE Connectivity Potter & Brumfield W58 series thermal circuit breaker providing resettable overcurrent protection for aircraft DC electrical systems. This 10-amp rated breaker uses series-trip operation to automatically open the circuit under overload conditions, protecting avionics feeders, lighting circuits, and other essential loads from electrical faults. The breaker resets manually after a trip event, eliminating the need for replacement fuses.
Install per aircraft maintenance manual specifications and FAA AC 43.13-1B wiring guidance, matching amperage rating to the protected circuit load.
