National Compressor Exchange 22a276s21 Motor Protector

Product Description

The NATIONAL COMPRESSOR EXCHANGE 22a276s21 is an original-style motor protector designed to safeguard compressor motors from thermal overload and electrical faults. This component monitors motor temperature and current draw, interrupting the circuit when unsafe conditions are detected to prevent motor burnout. It is a direct-fit replacement for the INT369R motor protector and is installed by licensed HVAC technicians and refrigeration service professionals as part of compressor maintenance or replacement service. At 0.5 pounds, it is a compact, lightweight component suited for service-van inventory.

This motor protector is typically used in residential and light-commercial refrigeration and air conditioning compressor applications. It is installed internally or externally on the compressor motor winding circuit to provide overcurrent and overtemperature protection. Techs replacing a failed compressor protector or servicing a compressor that has experienced thermal lockout will find this a direct replacement for the INT369R protector referenced in the original application.
