Value Brand Potential Relay 35A SPST 500V AC

SKU CH-HHBS-GGXZ3

35 A SPST potential relay with 500 V AC coil and pick-up between 332 V and 356 V AC

  • Handles 35 A loads for heavy-duty switching
  • Operates at 500 V AC coil voltage for high-voltage systems
  • Activates between 332 V and 356 V AC for precise control
  • Releases at 135 V AC drop-out to protect equipment
  • SPST mechanical design gives simple, reliable operation

HVAC Potential Relay for 35 A Circuits

This Value Brand relay switches single-phase loads up to 35 amps in HVAC control panels. It is built for technicians who need a mechanical potential relay with a 500 V AC coil voltage. The SPST contact form suits compressor start circuits that require a simple on-off action.

Direct Mounting with Fixed Pick-Up Range

The unit mounts using its 1 11/16 in height by 2 in width footprint. Pick-up voltage is factory-set between 332 V AC and 356 V AC with a maximum drop-out of 135 V AC, so no field adjustment is possible. Installers must verify that the system voltage stays within this narrow window before wiring.

35 Amp Contact Rating at 500 V AC Coil

The 35 A contact rating at 500 V AC coil voltage is the decisive specification. Systems demanding a higher current carry capacity or a different coil voltage cannot use this relay. Buyers who need adjustable pick-up settings or a multi-pole contact arrangement should select a different model.

Questions about this item

How can I confirm the relay is operating correctly after installation?

Verify the coil receives 500V AC and the contacts switch between the 332V AC pick-up threshold and the 135V AC drop-out level.

What does the package contain and what must I source separately?

The box includes the relay unit only; mounting hardware, wiring and any enclosure are not supplied.

Which version should I choose for a 35 A SPST circuit?

This single model is rated 35 A SPST at 500V AC with fixed pick-up and drop-out voltages, so no alternative version exists.
