This Phoenix Contact TCP thermal circuit breaker offers a compact solution for circuit protection, available in finely graded nominal current steps from 0.25A to 10A. This specific model, part number 0712275, is rated for 6A and operates at 250V AC or 65V DC.
Key features include a push-to-reset actuator, enabling immediate switching back on after triggering, which enhances system availability. The breaker can be plugged into UK 6-FSI/C fuse base terminal blocks with screw connection or ST 4-FSI/C terminals with spring-cage connection. Potential distribution is conveniently implemented using bridges with both terminal block types.
With an ambient temperature range of -20°C to +60°C, this circuit breaker is suitable for various environmental conditions. It boasts an interrupting capacity of 8 x I N for nominal currents of 6A to 10A, and 6 x I N for currents from 0.25A to 4A. The UL 1077 interrupting capacity is 2000A at 250V AC and 200A at 65V DC. The insulating material is PA with a V0 flammability class in accordance with UL 94.
The nominal voltage is 250 V AC (also rated for 65 V DC).
