Typical applications include:

• Industrial pumping systems
• Conveyor systems
• Air-handling units
• Machine-tool control panels

Key benefits:

• Helps protect against unsuitable supply voltage — Under and over voltage monitoring allows an external control circuit to inhibit equipment when the measured supply leaves the set voltage window.
• Helps prevent incorrect motor rotation — The relay requires correct phase sequence before energising, allowing a motor contactor to be inhibited when the incoming phases are reversed.
• Helps avoid operation after phase loss — The output relay de-energises on phase loss, allowing an external contactor or control input to inhibit equipment on an incomplete supply.
• Helps avoid unnecessary voltage-fault trips — An adjustable fault delay allows brief voltage deviations to be tolerated before the relay changes state, subject to the documented immediate-trip conditions.
