This Phoenix Contact 0712314 is a thermal circuit breaker designed for reliable circuit protection. It offers a nominal current of 10A and can operate at voltages up to 250V AC or 65V DC. The breaker features a compact design and an integrated ON/OFF switching function, allowing it to be switched back on immediately after triggering, which increases system availability.
The thermal circuit breaker TCP can be plugged into UK 6-FSI/C fuse base terminal blocks with screw connection technology and into ST 4-FSI/C terminals with spring-cage connection technology. Potential distribution can be conveniently implemented using bridges for both terminal block types. The ambient operating temperature range is from -20°C to +60°C.
Key electrical specifications include an interrupting capacity (ICN) of 6x IN for nominal currents up to 4A and 8x IN for nominal currents from 6A to 10A. Under UL 1077, the interrupting capacity is 2000A at 250V AC and 200A at 65V DC. The service life is rated for 3000 cycles at 1x IN (inductive) and 500 cycles at 2x IN (inductive).
This circuit breaker is designed for holder mounting and has a push-to-reset actuator. It meets IEC/DIN VDE standards and has a rated surge voltage of 2.5 kV. The insulating material is PA with a flammability class of V0 in accordance with UL 94.
