40A PCB relay for 3 phase systems with feedback contact

HE-R relay is the first printed relay which can be used as the main switching element in 3 phase systems. Due to its compact size, it enables the customer to bring the switching function on PCB. This contributes to considerable space & cost savings. Each of the 4 NO contacts is able to switch 40A up to an ambient temperature of +85°C - also a result of the sophisticated thermal design and an unique low coil holding power. An optional NC contact as feedback contact can handle low level loads down to 10mA / 5VDC. The IEC62955 compliant HE-R relay is a perfect option for demanding wallbox designs.
