Panasonic Industrial Devices HE-R Power Relays offer a 12VDC to 24VDC rate coil voltage range, 80A maximum switching current, and compact size. The HE-R series is an energy management relay constructed for 3-phase AC charging using its 4FormA contacts arrangement, simultaneously allowing for the cut-off of all 3 phases plus neutral. The featured auxiliary contact is used to detect welding failures of the primary open contacts, and these relays meet the necessary Short Circuit Current Rating (SCCR) to pass UL and IEC charging equipment. Panasonic HE-R Power Relays have a low coil-holding voltage for reduced power consumption and is PCB mounted to ease board assembly.
Panasonic has extended the HE-R series to include 2 Form A and 2 Form A 1 Form B contact arrangements with a maximum switching current of 80A at 277VAC designed for single-phase AC chargers (EVSE). These extension parts meet UL 508 standards for short circuit current rating (SCCR) with a 5000A rating.
