Thermal device circuit breakers

Thermal circuit breakers provide optimum protection against overload for your consumers in 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.

Advantages:

  • Reconnection options for fast, replacement part-free recommissioning after a fault
  • Easy to retrofit in existing systems with vehicle flat-type fuses with identical pin connector pattern
  • Disconnect the system from the power source for maintenance actions via the integrated device switch
