SCCR-Compliant Relay Designed to Replace Traditional Contactors
The HE-S SC Type Power Relay combines the high-current switching performance of an AC contactor with the compact size and efficiency of a PCB-mountable relay. Designed for EV charging, renewable energy, and industrial power applications, it delivers 40 A switching at up to 480 VAC while meeting IEC 62752 and IEC 62955 SCCR requirements.
A key advantage of the HE-S SC Type Relay is its certified Short-Circuit Current Rating (SCCR) compliance, making it particularly well-suited for three-phase EV charging equipment. An optional 1 Form B auxiliary contact with a mirror-contact structure compliant with EN 60947-4-1 enables contact-position monitoring and welded-contact detection, helping support functional safety requirements.
Compared to traditional contactors, the HE-S SC Type Power Relay offers equivalent switching performance in a much smaller footprint while consuming only 400 mW of holding power, reducing system energy consumption and heat generation. This Power Relay is available with 12 VDC or 24 VDC coils and features a 3.0 mm contact gap in a compact 36 mm × 30 mm × 40 mm package. Typical applications include EV charging stations and charging cables, photovoltaic power systems, inverters, elevators, and semiconductor inspection equipment.
