GENERAL FEATURES

Outstanding Features.

KLIXON® 6752-12 series thermal–magnetic circuit breakers are designed and manufactured to meet the more stringent military standards of today’s aircraft electrical systems. The interrupting capacity, vibration resistance and longer cycling life of the 6752-12 series exceed previous military standards. In addition, the 6752-12 series provide ambient compensation, fault coordination of all ratings, and an option for auxiliary circuits.

Features

Trip–free design
Single–phase
Ambient compensated
MIL-DTL-27715 qualified
Current rating: 2.5 to 65 amps
Long, trouble–free operation: 20,000 operating cycles
High vibration resistance
High interrupting capacity
Option available: Auxiliary circuits
Circuit protection unaffected by temperature fluctuations (ambient compensated from -53.9°C to 93.3°C)
Only faulted line circuits opened (coordination ratings insure that branch circuit breakers trip first under fault conditions)
Typical use: Aircraft electrical systems
