This circuit breaker is manufactured by Honeywell, a leading name in the aerospace industry, ensuring top-notch quality and performance.

The CM-15 model is a single-pole, normally open type circuit breaker, rated for a current of 15 amperes. Its unique design incorporates a bimetallic element that trips the breaker when the current flow exceeds the rated limit, preventing potential damage to the electrical system or aircraft.

This circuit breaker is specifically designed for use in aircraft applications, where safety and reliability are paramount. It meets the stringent requirements of various aviation and aerospace standards, including FAR-25, DO-160, and MIL-STD-790. Its robust construction, combined with its ability to withstand extreme temperatures and vibrations, makes it well-suited for the challenging environment of an aircraft.

The CM-15 5388GX7 circuit breaker is compact in size, with dimensions of approximately 3.0 inches in length, 1.5 inches in width, and 1.2 inches in height. Its lightweight design, coupled with its high breaking capacity, ensures minimal additional weight for the aircraft.

The breaker housing is made of a durable, high-strength material, providing protection against electrical surges and mechanical impact. Its terminals are silver-plated for improved conductivity and resistance to corrosion. The breaker also features a transparent window, allowing for easy visual inspection of the contacts.

The CM-15 5388GX7 circuit breaker comes with a built-in indicator, which illuminates when the breaker is in the tripped position. This feature allows for quick identification of any faults in the electrical system, facilitating prompt maintenance and repair.

Overall, the Klixon CM-15 5388GX7 15A CM Aircraft Circuit Breaker is a high-performance, reliable, and safe component for aviation electrical systems. Its rugged construction, combined with its ability to meet stringent aviation standards, makes it an essential choice for aircraft manufacturers, maintenance organizations, and operators.
