Phoenix Contact TCP Thermal Device Circuit Breakers

Phoenix Contact TCP Thermal Device Circuit Breakers provide optimum protection against overload for power distribution systems. When the circuit breaker trips, the integrated switch function enables immediate reactivation. Unlike a fuse, the circuit breaker does not need to be replaced. The higher the overload, the faster the thermal device circuit breaker trips. Phoenix Contact TCP Thermal Circuit Breakers include 16A and 20A plugs in a slim package for protecting devices with higher nominal currents.

Combined with the terminal block bases, these thermal circuit breakers can equip applications up to 250VAC and 65VDC with basic protection. TCP devices are well-suited for replacing existing fuses with re-closable variants, minimizing maintenance effort. The two-piece construction offers the convenience of a simple change-out. This Phoenix Contact series provides two distinct operational characteristics: on/off and trip reset or only trip reset.
