KLIXON® 7274 series are small, lightweight, low amperage devices that are specifically designed to protect aircraft/aerospace cable and components in airborne vehicles and equipment. The commercial grade version of this circuit breaker is the Klixon® 7277 series. The 7277 and 7274-2 series circuit breakers are physically and electrically identical, with the exception that the 7277 has wider calibration limits.
