KLIXON
DESCRIPTION
7274 Series Circuit Breaker
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.
Klixon 7274 series is designed for applications that do not require the tighter performance characteristics and approvals of our military circuit breakers.
Single Phase, Non-Compensated, Low Amp, General Application
- Miniature size
- Light weight
- Trip free design
- Current ratings (½ to 20 amps)
- High vibration resistance
