High Close-Off: Rated for a 200 psi close-off pressure

MARS 43331 Pressure Switch R-22 Incorporating an activated alumina andThe MARS 43331 Pressure Switch is a professional grade high pressure cutout designed for heavy duty HVACR applications. Engineered for precision, this SPST normally closed control features a fixed setpoint that triggers an open on pressure rise at 400 PSI and provides an automatic reset when system pressure drops to 300 PSI. This encapsulated pressure control is built to withstand harsh environments, utilizing a hermetically sealed sensor to ensure
