“The HE-R2A relay series is suited for modern wall box designs, and we are happy that we can offer a UL508-compliant sibling of the HE-R type for European four-phase systems, enabling the ...

With its ease of configuration and its comprehensive range of facilities, including a variable-frequency voltage source with a continuous phase-shift function, Megger’s new self-contained SVERKER 780 ...

The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a phase loss, phase reversal, phase unbalance, undervoltage or overvoltage condition ...

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...
