The 1963945 is a 3-amp aircraft circuit breaker designed for 14/28-Vdc electrical systems. This resettable, trip-free device protects avionics feeders and aircraft wiring from overloads and short circuits by automatically interrupting current when amperage exceeds the rated threshold. Panel-mounted installation provides overcurrent protection for equipment and wiring runs throughout the aircraft.
The breaker resets manually after a trip, eliminating the need for replacement fuses. Verify MS22073/MS25244 specification compliance and wire gauge compatibility before installation in certificated aircraft.
