Klixon 6TC series circuit breakers provide
ambient compensated circuit protection in a lightweight,
miniature package size. The three–phase integrally linked
design provides over current protection in the event of
simultaneous or unbalanced overloads, including short
circuit conditions.
Coordination
The 6TC series is compatible with the
single–phase 2TC and 3TC. The 6TC is available in ratings
from 2 to 20 amps, with military and various commercial
approvals on most styles.
Ambient Temperature Compensation
The 6TC 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 6TC 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 6TC.

Ambient Temperature Compensation
|
-54°C to 121°C
Especially suited for applications
where ambient temperature exceeds the 71°C (160°F) maximum
of non–ambient compensated thermal circuit breakers.
However, care should be taken to understand the
specification limits at elevated ambient temperatures.
