The LXPRC/S is a 3-phase voltage monitoring relay designed for monitoring undervoltage, overvoltage, phase loss and phase reversal. Typically used in conjunction with an external contactor, the relay/contactor are energised when the supply is healthy. If any of the above fault conditions occur, the relay/contactor de-energises, therefore, protecting the connected equipment.
This video demonstrates the operation of the relay when simulating phase loss on each phase in turn. The video also shows the operation of the relay when two phases are reversed.
