High Pressure Switch 200-400 PSIG

The SUPCO SHP400200 is a high pressure control switch designed for safety and disconnect applications. It operates within a fixed pressure range of 200 to 400 PSIG and features a 1/4 inch female flare connection. The switch uses an SPST contact form rated for 120/240VAC operation.

Fixed Range Safety Control

This switch suits systems requiring a non-adjustable high pressure cut-out with a factory-set differential. It is not for installers who need adjustable pressure settings or a different pressure range for their specific equipment. Buyers requiring a low pressure control or a switch with manual reset should look at other product types.

1/4 Inch Flare Integration

The female flare fitting connects directly to compatible refrigerant lines or pressure ports without additional adapters. Its fixed calibration removes the need for field adjustment tools during installation. The SPST wiring simplifies the electrical circuit for high pressure shutdown. California Proposition 65 warnings apply to this product.

Questions about this item

What existing 1/4 in flare pressure line and 120/240VAC circuit are required to install this SHP400200 switch?

The switch connects to a 1/4 inch female flare fitting and is rated for 120/240VAC SPST operation.

Can the fixed 200-400 PSIG range replace an older adjustable switch without changing wiring?

Yes, the SPST contact form and voltage rating match common legacy controls; only the non-adjustable pressure range differs.

How do I verify the switch opens and closes at the correct pressures after installation?

Pressurise the system and confirm the circuit breaks near 400 PSIG and remakes near 200 PSIG using a calibrated gauge.
