Three phase, Under voltage, Sequence and Loss
The product monitors it’s own three-phase supply and can be set for either 3-wire or 4-wire monitoring. For the output relay to energise, all phases (and neutral – if applicable) must be present, phase sequence correct and measured phase voltages above the set trip level. If any of these conditions are not met, the relay will de-energise.
