Overview

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.

Trip–Free
The 7274 features a trip–free, indicating reset button and is available in standard ratings from ˝ to 20 amps.

Wiping Action
A "wiping action" contact design assures low voltage drop, faster trip time and high reliability in low voltage applications. They are available in standard ratings from ˝ to 20 amps.

Water Resistant Panel
A water resistant panel seal designed to fit over the push button actuator is available for applications that require this type of protection. [Part #14500-1 fits 7274-11 and others with 15/32" (1.19 cm) mounting brushing. Part #14500-5 fits 7274-2 (7/16 bushing).]
