Power Relay 941D335 Series



The 941D335 Series Circuit Breaker (also sometimes referred to as a Contactor, Relay, or Power Relay) is/was manufactured or cataloged by Hamilton Sundstrand (a United Technologies Company). Part numbers within the 941D335 Series include but may not be limited to 941D335-2 and 941D335-4. The 941D335 Circuit Breaker 120/208 Vac, 3 Phase, 400 Hertz, is an electromagnetically operated, three pole, plunger-type solenoid unit. The main actuator assembly is held in the closed position by a permanent magnet latch circuit and held in the open position by a helical coil spring. Applied electrical power is required only to close (15 milliseconds duration) or trip (10 milliseconds duration) at a minimum of 15 volts DC. The circuit will operate as high as 35.5 volts DC. The rated and normal operation level is 28 volts DC. The main contacts are designed to interrupt or close and conduct 125 amperes, 400 hertz continuous. Typically, the 941D335 Series Circuit Breaker can be found on Heavy Jet aircraft within the Commercial and Military sectors.
