HE-R Series Relays

Compact Size Power Relays in Multiple Contact Arrangements for Energy Management Applications!

The Panasonic HE-R Series is an Energy Management Relay designed for single-phase or 3-phase AC charging units, combining High Capacity, High Switching, and Low Operating Power into a small size Power Relay.

The HE-R Series Relay also features a low coil-holding voltage for reduced power consumption and is PCB mounted to ease board assembly. This Relay also meets the necessary Short Circuit Current Rating (SCCR) to pass UL and IEC standards for EV charging equipment, making it suitable for charging stations, industrial equipment, and more.
