HE-A Series High-Capacity 110 A Power Relays

Panasonic HE-A series general power relays can achieve 90 A at 277 V_AC switching capacity and 110 A carry current within a compact size of 33 mm x 38 mm x 38.8 mm. These high-capacity relays also feature an optional normally closed auxiliary contact for contact position monitoring and weld detection. Both features make the Panasonic HE-A series general power relay a valid alternative for contactor replacement.

The HE-A series relays feature a 5 kA short-circuit current rating (SCCR) and a very low contact resistance, which allows for a UL rating of 110 A carry current. These relays also have a mirror contact mechanism with an auxiliary contact compliant with IEC60947-4-1 to allow for weld detection. The HE-A series relays feature a low coil holding power of 310 mW which improves power consumption and reduces the coil temperature rise. Offered in both 12 V_DC and 24 V_DC coils along with an optional 1FormB weld detection contact, these relays provide customers with a variety of options to choose from.
