P100C type controls feature SPST open-high switch action and automatic reset and are typically used for high-pressure cut-out applications. P100D type controls feature SPST open-high switch action and a manual-reset lockout mechanism for high-pressure lockout applications. P100E type controls are non-standard models that The low pressure closes (cuts-in) the switch on rise of compressor suction pressure and opens (cuts-out) the switch on pressure drop. The high pressure function overrides to open the switch as the compressor discharge pressure rises. Low Pressure (Open Low): 10" to 100 PSI, 10 to 40 PSI differential, automatic reset. by offering a wide range of pressure settings, port fittings and electrical connections. Its robust non-electric construction safely operates under high pressure conditions helping keep maintenance costs and return rates low. • Air Conditioning (R410a, R22, R134a, R407c CO 2 (R333a), Ammonia (R717)) • Engine Oil • Compressors & Pumps Purchase & Buy 80K52 - 80K52 80K5201 SWITCH PRESSURE HIGH R22 On Sale Today!

Choose from low and high pressure controls that can be used for R12, R22, R134A, R502 and other noncorrosive refrigerants. About Switch High Reset Pressure Manual . If air can't pass through then correctly, it will cause the freon pressure to rise and can trip the high pressure switch. The R22 manual and auto reset HP switches are 55000401 and 55000402 respectively. Plastic cam on manual lever assembly on the valve body broken.. Excessive motor heat can Ranco MPH-7111 - 475 Cut-Out, Manual Reset Cut-In High Pressure Cut Out - RANCO Mini Pressure fixed setting controls are used on refrigeration or air conditioning systems using R12, R22, or R502 refrigerants. Both low pressure (suction sensing) and high pressure (discharge or head pressure sensing) versions are available. Features SPST switch These pressure switches are designed for use in a variety of applications involving refrigeration high or low pressure. Models supplied have a "whole range" design, enabling them to be used with refrigerants R22, R134A, R404A, R410A, CO2 and all other non-corrosive refrigerants which are within the operating range of the control. The P77 & P78 series pressure controls may be used for KP pressure switches with auto reset are supplied with top cover. For KP pressure switches with manual reset, the top cover must be separately ordered (code no. 060-109766 for single pressure switches and code no. 060-109866 for dual pressure switches). IP55 to EN 60529 / IEC 60529 IP55 is obtained when the KP pressure switches PRESSURE CONTROLS O SERIES DUAL FUNCTION PRESSURE CONTROLS These controls offer a tailored variety of ranges and options for R12, R22, and R502 refrigerants. Low and high pressure functions are combined into a single control with one switch. FEAT
