  • Forewarns developing earth faults
  • Response range from 10 mA to 30 A
  • Communicates via Modbus RTU
  • Enables remote condition monitoring
  • Compact, space saving design

RCM410R is a residual current monitor or earth leakage relay. It continuously monitors earthed (TN and TT systems) for residual or fault currents when paired with a relevant current transformer (CT).

This AC and pulsed DC sensitive residual current monitor connects to existing communications networks, enabling remote condition monitoring. In the event of a fault occurring, an alarm will be issued against pre-set threshold values between 10 mA to 30 A without causing shut-down. Two separately adjustable response values allow a distinction to be made between prewarning and main alarm (prewarning = 50…100 % of the set residual operating current IΔn).

Highly accurate and cost effective this device supports the reduction of risk and operating costs in facilities such as manufacturing, electrical plant, data centres, hospitals and other critical infrastructure applications. It can also monitor single conductors e.g. PE conductors, N-PE bridges or PE-PAS bridges.

Easy configuration via app

With the NFC function and the Bender Connect App you can easily configure the RCM410R via a smartphone.
