RCMP20HC2-01

Current Sensors Overview

The RCMP20HC2-01 is a Residual Direct Current Monitoring module (RDC-M) from the RCMP20-01 series, designed for monitoring ground-fault, residual, or leakage currents in single-phase and multi-phase systems. It operates within a supply voltage range of 4.75V to 5.25V and withstands a surge current capacity of 3000A. The device detects residual currents ranging from 6mA to 56mA and features a fault signal output with an external test function. Designed for Mode 3 electric vehicle charging integration per IEC 62955 standards, it functions reliably across an operating temperature range of -40°C to +105°C.

Current Sensors Procurement Notes

Verify that the specific part number RCMP20HC2-01 matches the required RCMP20-01 series specifications for your design. Confirm compatibility with IEC 62955 standards if used in regulated markets. Ensure the host system provides the correct 4.75V to 5.25V supply voltage. Check thermal management requirements against the -40°C to +105°C operating range. Validate that the 3000A surge current rating meets the protection needs of the target application circuit.

Current Sensors Selection Notes

Select this module when integrating RCM functionality into Mode 3 EV chargers requiring compliance with IEC 62955. It is suitable for designs needing detection of low-level DC residual currents down to 6mA. Choose this component for applications demanding high surge immunity up to 3000A. It is appropriate for OEMs seeking a compact PCBA solution for electric vehicle charging control and protection.

Current Sensors Part Context

This component belongs to the RCMP20-01 series manufactured by Western Automation Research and Development, now part of Littelfuse. The series specializes in electrical shock protection devices for AC and DC environments.
