RCMP20HT-03

Current Sensors Overview

The RCMP20HT-03 is an AC/DC sensitive residual current monitoring module from the Littelfuse RCMP20 series. It continuously monitors ground fault, residual, or leakage currents in single-phase and multi-phase installations. Designed for Mode 2 electric vehicle charging stations, it complies with IEC 62752 standards to detect both AC and DC fault currents that standard A-type RCDs may miss. The module operates on a supply voltage of 4.75V to 5.25V and functions within a temperature range of -40°C to +105°C.

Current Sensors Feature Summary

• Monitors both AC and DC residual currents simultaneously
• Detects ground faults and leakage currents exceeding thresholds
• Generates trip signals when fault limits are surpassed
• Complies with IEC 62752 standards for IC-CPD integration

Current Sensors Applications

• Mode 2 portable cable control and protection devices (IC-CPD)
• Electric vehicle charging station safety systems
• Ground fault detection in residential EV setups
• Integration with A-type RCDs for enhanced protection

Current Sensors Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and mechanical configuration. Ensure compatibility with the intended switching device for circuit interruption. Confirm operating temperature ratings match the installation environment requirements before finalizing procurement decisions.

Current Sensors Selection Notes

Select this module for applications requiring simultaneous AC and DC residual current monitoring in Mode 2 EV charging contexts. It addresses limitations of standard A-type RCDs by detecting DC components. Ensure the design integrates a suitable switch mechanism to execute the trip signal generated by the monitor upon fault detection.

Current Sensors Part Context

This component belongs to the RCMP20 series of residual current monitors designed for electric vehicle infrastructure. It complements the RCMP20-01 series, which targets Mode 3 permanent connections. The RCMP20HT-03 specifically supports portable charging solutions where detecting mixed AC/DC faults is critical for user safety and regulatory compliance.
