Saginomiya DNS-D606M is a dual high-low pressure switch designed for refrigeration compressors on marine & industrial chiller units. It independently monitors suction(low pressure) and discharge(high pressure) of refrigerant circuit, cutting off compressor power automatically when pressure exceeds preset limits.
High-pressure side adopts manual push-to-reset protection while low-pressure is auto-reset, effectively safeguarding refrigeration equipment against overpressure and low-pressure loss.
