Product Overview
The HCT632S-15EMI is a residual current sensor designed for advanced residual current detection. It integrates an A+6 residual current detection circuit capable of sensing various leakage current waveforms. Featuring a low-power consumption, high precision, excellent linearity, strong anti-interference capabilities, minimal temperature drift, and isolated current detection, this sensor is ideal for demanding applications. Its compact design, precise tripping thresholds, and robust resistance to external magnetic fields (up to 35mT) and strong EMC interference make it a reliable choice. The sensor is suitable for 120V, 250V, and 380V power systems, applicable to both single-phase and three-phase configurations. It meets IEC 62752 Mode 2 IC-CPD and IEC 62955 Mode 3 RDC-DD charging-related residual current testing requirements, as well as DC6mA testing needs.
