EC-E4 10A - Electronic circuit breaker

Electronic circuit breaker, signal contact: 1 N/C contact, nominal current: 10 A

  • Error-free short-circuit detection even across long cable paths with the electronics characteristic curve
  • Active current limitation to improve the capacity of the upstream power supply
  • Increased system transparency with integrated floating remote indication contact (N/O)
Technical Specifications

Notes

GeneralWhen mounted in rows without convection cooling, the nominal device current should only be led to a maximum of 80% due to the thermal effect during continuous operation (100% operating factor).Special precautionary measures must be taken in systems or machines, to prevent components from restarting (e.g., use of a safety PLC).Parallel connection of multiple circuit breakers is not permitted.
