Type Residual Current Device Miniature Circuit Breaker
Features
  • True IP2X finger-safe design (front)

  • For applications in which AC and pulsating DC fault currents are likely to appear, nonselective and non-delayed

  • Designed to prevent unwanted tripping caused by switching electronic circuit devices

  • Auxiliary and Signal contacts may be added
    		•
  • True IP2X finger-safe design (front)

  • Energy Limiting Design protects downstream components better than conventional breakers during short circuits

  • Field mountable options for selective applications

  • AC and DC voltage ratings in one convenient device

  • Superior shock and vibration resistance capabilities

  • Mounts on hut (DIN) rail
