HE-A General Power Relays
Panasonic Industry HE-A General Power Relays are high-capacity relays that achieve a maximum switching current of 90A (inductive) and a carry current of 110A. These power relays include an optional normally closed auxiliary contact for contact position monitoring and weld detection. Panasonic Industry HE-A General Power Relays also include a mirror contact mechanism with an auxiliary contact compliant with IEC 60947-4-1, enabling weld detection. Additional features include a 5kA short-circuit current rating (SCCR), low coil-holding power of 310mW, and a 3.6mm initial minimum contact gap (Form A). The HE-A relays are available in 12VDC and 24VDC coils, along with an optional 1 Form B weld detection contact in a compact 33mm x 38mm x 38.8mm size. The relays are used in photovoltaic (PV) inverters, solar panels, electric vehicle supply equipment (EVSE), and level 2 EV charging stations.
