Western Automation RCM Residual Current Monitors

Western Automation RCM Residual Current Monitors offer a 12VDC to 24VDC voltage range and a 6mA to 56mA residual operating current. These monitors are intended for the detection of DC and AC residual currents in UL 2231 electric vehicle (EV) charging systems where such current may flow under a fault condition. RCM monitors feature an external test facility, "fault" signal output, and 3000A surge current withstand capability. Western Automation RCM Residual Current Monitors can be mounted directly onto a printed circuit board by OEMs and have an operating temperature range of -40°C to +85°C.
