Panasonic Industrial Devices HE-R Power Relays
Panasonic Industrial Devices HE-R Power Relays offer a 12VDC to 24VDC rate coil voltage range and 80A maximum switching current in a compact size. The HE-R series is an energy management relay constructed for three-phase AC charging using its 4FormA contacts arrangement, simultaneously allowing for the cut-off of all three 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 provide a low coil-holding voltage for reduced power consumption and are 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 SCCR with a 5000A rating.
