  Key Features

  • Highly sensitive residual current detection.

  • Rectangular measuring aperture for large cables and busbars.

  • Solid-core transformer construction.

  • Converts residual currents into evaluable measurement signals.

  • Compatible with selected Bender RCM, RCMS, and EDS systems.

  • Designed for continuous industrial operation.

  Applications

  • Insulation fault monitoring systems

  • Residual current monitoring

  • Industrial power distribution panels

  • Electrical cable and busbar monitoring

  • Industrial AC and DC electrical installations

  Important Notes

   

  • This is a measuring current transformer, not a standalone insulation monitoring device.

  • Compatible equipment includes Bender RCMS460/490, RCM420, and EDS440/460/490 systems.

  • Internal opening dimensions are 70 × 175 mm; check cable and busbar clearance before installation.

  • The WR70x175S has no integrated screening. Do not confuse it with the WR70x175SP version (B911790), which includes screening.
