KLIXON CIRCUIT BREAKER/15 AMP

KLIXON CIRCUIT BREAKER/15 AMP 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 15 through 35 amperes. The 3TC is available in 15 to 35 amps.

Coordination
The 3TC single–phase and three–phase breaker ratings are coordinated so that in the event of a fault of up to 6,000 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
Ambient compensated circuit breakers permit 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 TC 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.

High Short Circuit Capacity
For its miniature size, the 3TC series offers unusually high current interrupting capacity. Overloads up to 6,000 amps at 28 VDC or 2,000–3,500 amps at 120 VAC, 400 Hz can be safely interrupted without affecting calibration or operating performance in the standard 3TC series.
