Lovato PMV Phase Monitoring Relays | Phase Failure, Sequence & Voltage Protection

Lovato PMV monitoring relays supervise three-phase supplies before enabling the control circuit. Different models monitor phase sequence, phase failure, asymmetry or voltage limits. Select the model for its documented functions and rated network voltage; PMV20A575 covers 208-575V, while PMV40A575 and PMV50A575 cover 380-575V according to the official catalog.

Features and applications

• Model-specific phase monitoring functions
• Output relay interfaces with the contactor control circuit
• PMV10A440, PMV20A575, PMV40A575 and PMV50A575 listed
• Supply range and thresholds must match the installation

Selection and installation

Use the exact monitored-voltage range and protection functions from the selected model. This is a control relay, not a load-carrying circuit breaker.

Available from Spark in Egypt for control-panel assembly, maintenance and electrical projects, with delivery to Cairo, Giza, Alexandria and other governorates. Match the order code, electrical ratings and compatible equipment before ordering.
