RCM14-04 SYSTEM CT

Current Sensors Overview

The RCM14-04 SYSTEM CT is a vertical current transformer component within the RCM14 series, manufactured by Littelfuse/Western Automation. It functions as a residual current monitor designed to detect AC and DC ground fault currents. The device features a single-channel configuration with a specified sensing capability of 6mA. It is engineered for panel mounting applications, utilizing a JST connector to facilitate straightforward installation. This system serves as a critical safety mechanism in electrical circuits.

Current Sensors Feature Summary

• Detects both AC and DC ground fault currents to identify leakage paths
• Triggers a fault output signal to disable charging current and mitigate shock hazards
• Designed for compact panel mounting with integrated JST connector for simplified wiring

Current Sensors Applications

• EV charging station safety systems
• Residual current monitoring in electrical distribution panels
• Ground fault detection for branch circuits requiring UL2231 compliance

Current Sensors Procurement Notes

Verify that the specific part number matches the required vertical current transformer configuration rather than standard PCB assemblies. Confirm compatibility with existing control interfaces via the JST connector. Ensure the unit meets local regulatory standards for residual current monitoring. Cross-reference manufacturer documentation to validate the 6mA sensing specification against system requirements before procurement.

Current Sensors Selection Notes

Select this component when AC and DC ground fault detection is required for safety-critical applications. The vertical form factor and JST interface suit space-constrained panel installations. Consider the 6mA sensitivity threshold for precise leakage detection. Verify UL2231 compliance needs for the target application environment. Evaluate integration complexity based on the single-channel design and dedicated fault output functionality.
