Product Description

The RANCO O Series Dual Pressure Control (MPN o12-1594) is a SPST dual pressure control with a low-side range of 10 in Hg to 100 psi and a high-side range of 150 psi to 450 psi, housed in a NEMA 1 enclosure.

Frequently Asked Questions

What is a RANCO O Series dual pressure control used for?

A RANCO O Series dual pressure control protects refrigeration and HVAC compressors by monitoring both low-side and high-side pressures. It cuts out on low pressure (10 in Hg to 100 psi) and high pressure (150 psi to 450 psi) to prevent damage from loss of charge or overpressure.

What are the specifications of the RANCO dual pressure control o12-1594?

The RANCO O Series dual pressure control (MPN o12-1594) is a SPST switch with a low-side range of 10 in Hg to 100 psi and a high-side range of 150 psi to 450 psi. It comes in a NEMA 1 enclosure for indoor use.
