Klixon
9TC

Klixon 9TC series circuit breakers provide ambient compensated circuit protection in a lightweight, sub-miniature package size. The three–phase integrally linked design provides overcurrent protection in the event of simultaneous or unbalanced overloads, including short circuit conditions.

Coordination
The 9TC series is compatible with the single–phase 2TC and 3TC. The 9TC is available in ratings in 1 amp and from 15 to 35 amps. Military and various commercial approvals are available on most styles.

Ambient Temperature Compensation
The 9TC serves as an ambient-compensated circuit breaker. This permits system designers to specify smaller gauge wire where the circuit breaker and wiring are exposed to different ambient temperatures.

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 9TC series offers unusually high current interrupting capacity. Overloads up to 2,000 amps at 120 VAC, 400 Hz can be safely interrupted without affecting calibration or operating performance in the standard 9TC.
