RCMP20VT-03

Current Sensors Overview

The RCMP20VT-03 is a residual current monitoring module from the RCMP20-03 series, manufactured by Littelfuse/Western Automation. It continuously monitors AC and DC residual currents to detect ground faults or leakage currents in electrical systems. The device operates within a supply voltage range of 4.75V to 5.25V and functions reliably across an operating temperature range of -40°C to +85°C. Designed for safety applications, it supports Mode 2 EV charger configurations and provides essential protection against electric shock risks during charging processes.

Current Sensors Feature Summary

• Continuously monitors both AC and DC residual currents for ground fault detection
• Provides protection against electric shock risks during EV charging operations
• Supports Mode 2 EV charger configurations with single pass-through design

Current Sensors Applications

• Mode 2 Electric Vehicle (EV) charger implementations
• AC and DC EV charging system residual current monitoring
• Ground fault detection in residential and commercial EVSE units

Current Sensors Procurement Notes

Verify that the specific suffix VT-03 corresponds to the intended Mode 2 configuration and voltage specifications. Confirm compatibility with existing PCB layouts and communication interfaces before integration. Ensure ordering documentation matches the exact part number to avoid functional mismatches in safety-critical EV charging applications.

Current Sensors Selection Notes

Select this module when continuous AC/DC residual current monitoring is required for Mode 2 EV chargers. Consider its wide operating temperature range and unidirectional sensor design for robust performance in various environmental conditions. Evaluate integration requirements with control circuits and communication ports for complete EVSE functionality.

Current Sensors Part Context

This component belongs to the RCMP20-03 series of residual current monitors from Western Automation, now part of Littelfuse. These modules are designed for high-sensitivity detection of leakage currents in EV charging infrastructure. The series offers reliable protection against electric shock hazards by monitoring ground fault currents in both AC and DC modes.

Current Sensors Replacement Considerations

Check RCMP20VC4-03 and RCMP20VT-01 as potential alternatives within the same series. Verify functional equivalence regarding Mode 2 support and residual current detection capabilities before substitution.
