Description
The Copeland 940-0150-51 is a genuine OEM current relay designed to support reliable single-phase compressor motor starting in refrigeration and air conditioning applications. Current relays play a critical role in the start-up sequence of hermetic and semi-hermetic compressors — they sense the high inrush current drawn by the start winding during motor start-up, then open the start circuit once the motor reaches operating speed, protecting both the motor and the start capacitor from prolonged energization.
