Current rating: 20 to 50 amps
Coordinated ratings
 
High vibration resistance
High interrupting capacity
Options include: standard or auxiliary switch configuration, terminal barriers
Typical use: Aircraft, avionics and electronic systems


Klixon single–phase TC devices are the smallest, lightest, high performance aircraft circuit breakers available today. They represent the state-of-the-art protection of today’s aerospace power systems. Their light weight and small size make them especially well suited for aircraft, avionics and electronic systems.

The Klixon trademark has set the standard for aerospace circuit breakers. For a small, light weight configuration, the TC series offers the endurance and reliability required by exacting military specifications, and are available in standard current ratings from 1 through 50 amperes.

Aircraft Circuit Breakers
Coordination
The single–phase 5TC breaker rating is coordinated so that in the event of a fault of up to 600 amps let–through current any rating will trip before another circuit breaker twice its rating. This results in improved overall equipment performance since only the smallest faulted circuit is interrupted, while larger circuits remain operational.

Ambient Temperature Compensation
The 5TC serves as an ambient compensated circuit breaker permits system designers to specify smaller gauge wire where the circuit breaker and wiring are exposed to different ambient temperatures.

They are especially suited for application where ambient temperature exceeds the 160°F (71°C) maximum of non–ambient compensated thermal circuit breakers. The 5TC series may be applied where operating temperatures are as high as 250°F (121°C), with no derating of the circuit breaker. This eliminates the need for cooling air and allows substantial weight, space and cost savings.

Trip–Free
The complete line of TC series circuit breakers is trip–free. The circuit breaker cannot be maintained closed during an overload even with the actuator button held closed.
