Description

Klixon 7277-2 series circuit breakers are meant for use in applications that do not require military approvals. The trip-free 7277 was originally developed as an alternative to slow blow fuses and is used extensively as primary electrical circuit protection on general aviation aircraft. The military grade version of this circuit breaker is physically and electrically identical to the Klixon 7277, which has wider calibration limits. Includes hardware.
