Klixon
Aircraft Circuit Breakers

Klixon 6752-300 series thermal–magnetic circuit breakers are designed and manufactured to meet more stringent military standards of today’s jet aircraft electrical systems. The higher interrupting capacity, vibration resistance and longer cycling life exceeds previous military standards.

Coordination
The 6752-300 series breaker ratings are coordinated so any rating will trip before another rating twice its capacity in the event of a fault. This results in improved overall equipment performance since only the smallest faulted circuit is removed while larger circuits remain in operation.

Auxiliary Circuit
The 6752-300 is available with auxiliary switch. For part numbers and characteristics, please contact Sensata Technologies
