RCMP20VC3-03

Current Sensors Overview

The RCMP20VC3-03 is a unidirectional current sensor module from the RCMP20-03 series, designed for monitoring ground fault and residual currents. It detects AC and DC leakage currents with a sensitivity of 6mA. The device operates within a supply voltage range of 4.75V to 5.25V and functions reliably in temperatures from -40°C to +105°C. Packaged as a module, it provides a current output signal suitable for integration into protection circuits.

Current Sensors Feature Summary

• Monitors both AC and DC ground fault, residual, or leakage currents
• Provides unidirectional current output signal
• Capable of detecting low-level DC fault currents starting at 6mA
• Designed for robust operation across wide industrial temperature ranges

Current Sensors Applications

• Ground fault circuit interrupter (GFCI) systems
• Residual current monitoring in EV charging infrastructure
• Leakage current detection in single-phase power systems
• Electrical shock protection devices

Current Sensors Procurement Notes

Verify that the specific suffix VC3 corresponds to the unidirectional configuration and 6mA sensitivity requirements. Confirm the module package type matches the target PCB layout. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the manufacturer's latest documentation to confirm pinout and electrical characteristics before integration.

Current Sensors Selection Notes

Select this component when unidirectional monitoring of combined AC and DC residual currents is required. The 6mA sensitivity makes it suitable for applications demanding early detection of small leakage faults. Verify compatibility with the system's supply voltage limits and thermal management capabilities. Consider the module form factor for ease of installation in existing control boards.

Current Sensors Part Context

This part belongs to the RCMP20-03 series manufactured by Western Automation Research and Development, now part of Littelfuse. The series specializes in electrical shock protection technologies. These sensors are engineered to detect dangerous leakage currents in various power distribution scenarios, enhancing safety in residential, commercial, and industrial electrical networks.

Current Sensors Replacement Considerations

Check for RCMP20VC4-03 if bidirectional sensing is needed instead of unidirectional. Verify RCMP20HT-03 for potential thermal or packaging differences within the same series. Consult official substitution lists to ensure functional equivalence in ground fault detection.
