Product Overview
The HCT632S-18EMI is a residual current sensor designed for detecting various leakage current waveforms. It integrates a detection circuit and a micro-processing unit, offering low power consumption, high accuracy, good linearity, strong anti-interference capabilities, minimal temperature drift, and isolated current detection. This sensor features a compact design, direct output of tripping levels, precise action thresholds, resistance to strong magnetic fields (up to 30mT), robust EMC performance, intelligent computation, and fast response times. It is suitable for 120V, 250V, and 380V power systems, applicable to both single-phase and three-phase configurations. The product meets IEC 62752 Mode II IC-CPD and IEC 62955 Mode III RDC-DD charging-related residual current test requirements, and is compatible with DC6mA test demands. It is ideal for isolated DC and AC leakage current detection and serves as a dedicated A+6 type residual current protection module for charging piles.
