Ranco 017-4701 R/A Low/High Pressure Switch
The Ranco 017-4701 is a dual-function (high and low pressure) pressure switch designed to protect refrigeration and air conditioning systems. The R/A designation indicates that the device features automatic reset (Auto/Auto) for both low and high pressure.
Protection: It shuts off the compressor in case of excessively low suction pressure (lack of refrigerant, icing) or excessively high discharge pressure (dirty condenser, fan failure).
Adjustment: Adjustment is made using the screws located on the top of the device. The graduated scale on the front panel (in bar and psi) allows you to visualize the cut-off points. Compatibility: Suitable for most common refrigerants (HFC, etc.)
Technical Specifications
Function: Combined control of low pressure (LP) and high pressure (HP) in a single unit.
Reset Type: Automatic on both sides (LP and HP).
Adjustment Ranges:
Low Pressure (LP): -0.3 to 7 bar (approx. 10" Hg at 100 psi).
High Pressure (HP): 7 to 30 bar (or 6 to 32 bar depending on regional variations).
Differential
LP: Adjustable from 0.6 to 4 bar (or 1 to 5 bar depending on the specific model). HP: Fixed at approximately 3.5 - 5 bar.
Electrical Connection: Single-pole changeover contact (SPDT) typically rated for 16(16)A at 250V~.
Fluid Connection: 1/4" SAE male (7/16-20 UNF)
