The 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.
The 6752-12 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 interrupted, while larger circuits remain operational.
Ambient Temperature Compensation
Substantially unaffected by ambient temperature, the 6752-12 circuit breakers maintain their performance capabilities by means of a thermal compensator in the temperature range of -53.9°C to 93.3°C.
High Short Circuit Capacity
A de–ionizing grid and magnetic assist enable the 6752-12 to successfully interrupt four fault currents of 6,000 amperes — two at sea level and two at 60,000 feet — on either a 120 VAC, 400 Hz system or a 30 VDC system.
The 6752-12 is available with auxiliary switch. For part numbers and characteristics, please contact Sensata Technologies
