Panasonic HE-R Series Power Relays

Panasonic HE-R Series Power Relays are compact size 4 Form A and 4 Form A 1 Form B 40A power devices with a maximum switching current of 50A. The HE-R series stands out as an energy management relay specifically designed for 3-phase AC charging, and also a 2 FormA contacts arrangement to enable the simultaneous cut-off of all three phases plus neutral. These power relays feature a low coil-holding voltage, reducing power consumption, and their PCB-mounted design streamlines board assembly. The HE-R relays can operate within the maximum temperature range from -40°C to +85°C with a minimum insulation resistance of 1000MΩ. Typical applications include Electric vehicle charging (EVSE), industrial power generation, 3-phase AC chargers, and industrial power supply equipment.
