Product Details
The YK-03H High Pressure Switch is a compact capsule safety control engineered for direct mounting in air conditioning and commercial refrigeration systems. Designed with an automatic reset mechanism, this switch safeguards compressors against excessive discharge pressure by opening the electrical circuit at 410 ± 15 PSI (~28.3 bar) and automatically resetting when head pressure drops to 310 ± 15 PSI (~21.4 bar). Featuring a 1/4in female flare brass connection with an internal valve depressor and pre-wired insulated leads, it provides dependable, factory-calibrated high-pressure protection for refrigeration engineers and OEMs.
