Potential relay for HVAC motor control

The Value Brand potential relay is a single-pole single-throw mechanical switch rated for 35 amps. It is designed for HVAC control circuits that need a voltage-operated start relay for single-phase motors. The coil operates at 375 volts AC with a pick-up range of 185 to 200 volts AC and a maximum drop-out of 105 volts AC.

Simple two-wire coil connection

Installation requires wiring the coil across the motor start winding so the relay energises when voltage reaches the 185 to 200 volt window and opens once voltage falls to 105 volts or below. Because the pick-up and drop-out points are not adjustable, the relay must match the motor's voltage profile exactly; a mismatch will prevent the start capacitor from disconnecting at the correct moment.

Verify motor start-winding voltage before ordering

Check that the motor's start-winding voltage falls within the 185 to 200 volt pick-up band and that the drop-out voltage does not exceed 105 volts. The contact rating of 35 amps must also exceed the motor's locked-rotor current. This relay is not suitable for systems that require adjustable timing or voltage-sensing operation.

Questions about this item

How do I verify the relay picks up and drops out at the correct voltages after wiring it?

Apply AC voltage to the coil and confirm the contacts close between 185 V and 200 V, then reduce voltage and confirm they open at or below 105 V.

What comes in the box and do I need any extra mounting hardware or wiring accessories?

The package contains the potential relay only; mounting brackets, screws and wire connectors are not included and must be sourced separately.

Which coil voltage version should I select for a system that runs at 375 V AC?

Choose the 375 V AC coil version listed, as it matches the specified coil voltage for this relay.
