This Carrier HK02ZB421 is a high pressure switch used to monitor refrigerant pressure in the system's high side. It opens its contacts when pressure rises to 610 PSI and resets once pressure drops back to 420 PSI, protecting the compressor from damage caused by excessive discharge pressure. This is a genuine Carrier replacement part. Confirm this part number against your equipment's parts list before ordering.
