The LINETRAXX^® RCMS150 is able to measure residual currents up to IΔ = 500 mA in a frequency range of DC…2 kHz. It is suitable for applications with a load current of up to 32 A. Two separately adjustable response values allow a distinction to be made between prewarning and alarm.

The devices feature an RS-485 interface with either BMS protocol or Modbus RTU which can be used to transfer measured values and alarm values. Setting parameters is also possible via this interface.
