CBM E4 24DC/0.5-10A NO-R - Electronic circuit breaker

Multi-channel, electronic circuit breaker with active current limitation for protecting four loads at 24 V DC in the event of overload and short circuit. With nominal current assistant and electronic locking of the set nominal currents. For installation on DIN rails.

  • Easy to configure, thanks to the nominal current assistant
  • Active current limitation to improve the capacity of the upstream power supply
  • Adjustable in increments per channel: from 0.5 A to 10 A
  • Easy system monitoring with early signaling and direct pickup of information at the product
  • Increased system availability with intelligent detection of under- and overvoltage
