BREAKER (P/N 7277-2-5) - As Removed, New Surplus

The 7277-2-5 is a 5-ampere push-pull thermal circuit breaker for aircraft electrical systems. This Klixon 7277 series breaker protects individual branch circuits from overcurrent conditions, automatically tripping to disconnect power when current exceeds the rated 5 A threshold. The trip-free design prevents manual override, ensuring protection remains active even if the switch is held in the ON position.

Install per aircraft wiring diagram, confirming the 5 A rating matches the protected circuit load. Common on general aviation and commercial aircraft electrical panels.
