RCMP20VC4-03

Current Sensors Overview

The RCMP20VC4-03 is a unidirectional current sensor module from the RCMP20-03 series, designed for residual current monitoring. It operates on a 5V supply (4.75V to 5.25V) and detects ground fault or leakage currents. The device features a through-hole mounting type and provides a current output. It supports frequencies of 50Hz to 60Hz and functions within an operating temperature range of -40°C to 105°C. The unit has a response time of 10 seconds and is packaged in a tray.

Current Sensors Feature Summary

• Monitors AC/DC sensitive residual, ground fault, and leakage currents
• Provides unidirectional current output for circuit protection applications

Current Sensors Applications

• Residential EV charging systems
• Commercial EV charging infrastructure
• Industrial EVSE integration

Current Sensors Procurement Notes

Verify that the specific suffix VC4-03 matches the required sensitivity and configuration for your design. Confirm the through-hole package style and tray packaging details align with your assembly process. Ensure the 5V supply voltage and 10-second response time meet the system's timing requirements. Cross-reference the operating temperature range against your environmental specifications.

Current Sensors Selection Notes

Select this module when AC/DC residual current detection is required for EV charging safety compliance. The unidirectional nature suits specific polarity monitoring needs. Consider the 10-second response time for fault clearance strategies. The wide temperature range allows deployment in harsh outdoor environments typical of public charging stations.

Current Sensors Part Context

This component belongs to the RCMP20-03 series by Western Automation, a Littelfuse company. The series specializes in remaining current monitoring technology to reduce electric shock risks during AC and DC EV charging. These modules are integral to OEM EVSE designs ensuring adherence to safety standards like IEC 61851.

Current Sensors Replacement Considerations

Consult official substitution lists for other RCMP20-03 variants. Verify if alternative suffixes offer different sensitivities or configurations suitable for the same application without altering the core monitoring function.
