Bulletin 1492-RCD Residual Current Devices

Bulletin 1492-RCD Residual Current Devices detect earth leakage. Use them in association with Bulletin 1492-SP miniature circuit breakers. Our residual current devices are available in 2- or 4-pole construction with four sensitivity settings. You can choose the appropriate level of protection for personnel or equipment from a wide range of currents and rated trip currents.

Features

  • True IP2X finger-safe design (front)
  • Undelayed tripping time
  • Line-voltage independent tripping (suitable for residual current & additional protection)
  • For applications in which AC and pulsating DC fault currents are likely to appear, nonselective and non-delayed
  • Prevents unwanted tripping caused by switching electronic circuit devices
  • Mounts on DIN rail
  • Busbar position on top or bottom
