CBMC E4 24DC/1-10A NO - Electronic circuit breaker

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

  • Easy device replacement without replanning, thanks to compact design and options for individual adjustments
  • Circuits can be adjusted without any tools by means of one single pushable LED button
  • Reliable protection against unintentional adjustment of current values, thanks to electronic locking
  • Status LEDs in traffic light colors enable instantaneous determination of operating states
