Supco OV38 is a universal motor overload protector designed for small refrigeration compressors. It uses a built-in temperature-activated disc to open and close the motor overload contacts, providing thermal protection for the compressor. The OV38 is specified for compressors from 1/5 to 1/2 HP and a locked-rotor current range of about 18.5 to 22 A. This compact overload device is a common replacement part in refrigeration and air-conditioning circuits that require a universal motor overload protector.
