JOHNSON DPST PRESSURE CONTROL

P72CA-13C JOHNSON CONTROLS DPST PRESSURE CONTROL 50/300 PSIG 36 INCH CAP WITH 1/4 INCH FLARE Features - All-steel case and cover built to provide long lasting, rugged protection for internal components. - “Sight-Set” calibrated pressure adjustment displays a visible pressure scale, fully adjustable through the range without removing the cover (on NEMA 1 enclosure models) - MICRO-SET differential option allows for precise control on low pressure applications - Independent high- and low-pressure switches (P70S and P170S Models) satisfies a variety of dual pressure application wiring requirements with a single versatile control - Convertible high pressure reset–auto reset or manual reset lockout (P70S and P170S Models) reduces inventory— one control can be adapted to several dual pressure applications in the field Applications - P72 models have a Double-Pole Single Throw (DPST) switch with load-carrying contacts that can provide direct control of 208-240 VAC, single-phase motors up to 3 hp, and 208-220 VAC, 3-phase motors up to 5 hp. The P70, P72, and P170 controls for low pressure applications are designed primarily for low pressure cut-out control, pump-down control, and capacity control on commercial refrigeration and air conditioning applications. These controls are available in several pressure ranges and are compatible with most common refrigerants. Ammonia compatible models are also available. These controls respond directly to system pressure changes on both high and low sides, and can provide single-device control of the compressor.
