Klixon® 5TC50 single–phase TC devices are the smallest, lightest, high performance aircraft circuit breakers available today. They represent the state-of-the-art protection of today’s aerospace power systems. Their light weight and small size make them especially well suited for aircraft, avionics and electronic systems. The 5TC50 breaker rating is coordinated so it will trip before another circuit breaker, twice its rating, in the event of a fault of up to 600 amps let through current. This results in improved overall equipment performance, since only the smallest faulted circuit is interrupted, while larger circuits remain operational.
Includes hardware.
This 5TC50 series circuit breaker (Alternate Part# 5TC50-50) is rated for 50 amps.
