| 6752-12 SERIES

2½ to 65 Amp, Single–Phase, Ambient Compensated

Introduction

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.

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
