Compact Size 1Form A / 1Form A 1 Form B 110A Power Relays!
Panasonic, a worldwide leader in Relay Products, introduces the NEW HE-A Series General Power Relays from Panasonic! These new high-capacity Relays can achieve 90A @ 277 VAC switching capacity, and 110A carry current within a compact size of 33 x 38 x 38.8mm. They also feature an optional, normally closed auxiliary contact for contact position monitoring and weld detection. Both features make the HE-A Series General Power Relay a valid alternative for contactor replacement.
The HE-A Series Relays feature a 5kA Short Circuit Current Rating (SCCR) and a very low contact resistance, which allows for a UL rating of 110A 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 310mW, which improves power consumption and reduces the coil temperature rise. Offered in both 12V DC and 24V DC coils, along with an optional 1FormB weld detection contact, these Panasonic Relays provide customers with a variety of options to choose from.
