RCM14-01_SYS_V is listed in the Current Sensors range at ChipApex. The manufacturer field lists Littelfuse/Western Automation. Its product description is RCM14-01 SYSTEM, CONSISTS OF 901. Review the specifications below when checking this part for your BOM.
The RCM14-01_SYS_V is a residual current monitor designed for Mode 3 EV charging systems to detect DC residual currents. It operates on a 10.8V to 13.2V supply with a maximum current of 14.5mA. The device supports 50Hz/60Hz frequencies and functions within a temperature range of -40°C to 85°C. It utilizes chassis mounting for integration into electric vehicle supply equipment (EVSE).
Verify the specific suffix V against official Littelfuse/Western Automation documentation to confirm exact electrical tolerances and configuration options. Ensure compatibility with the target chassis mounting environment and supply voltage range of 10.8V to 13.2V before procurement.
Select this component for applications requiring dedicated DC residual current monitoring in Mode 3 EV chargers. Consider the 14.5mA max supply current and -40°C to 85°C operating range when designing thermal and power management strategies for the host EVSE unit.
This part belongs to the RCM series from Western Automation, a Littelfuse company. The series focuses on ground fault protection for electric mobility, offering monitors that detect both AC and DC leakage currents to prevent shock hazards during charging operations.
Consult official Littelfuse/Western Automation substitution guides for verified alternatives. Generic RCM devices may not match the specific DC detection thresholds or Mode 3 compliance requirements of this model.
It is intended for the detection of DC residual currents in 50Hz/60Hz AC installations and Mode 3 EV charging systems.
It quickly triggers a fault output to disable the charging current and remove the fault condition.
