Common failures and maintenance of overload protectors for air-conditioning compressors

Overload protector of air conditioner compressor Installed between the active and passive sides of the power transmission, when an overload fault occurs (torque exceeds the set value), the torque limiter will separate, thereby effectively protecting the driving machinery and the load. Just like its name, the fundamental function of the overload protector is to protect the air-conditioning compressor.
