Copeland 940-0001-54 Start Relay

The Copeland 940-0001-54 Start Relay is an essential part that starts compressors in HVAC systems with precision and reliability. As a start relay, it connects the compressor motor's start winding to the power source for moments. This relay rated at 375 VAC with a frequency of 60 Hz has been designed to match electrical needs of different kinds of systems for heating, ventilation and air conditioning. The start relay receives signals from the thermostat or control system, which cause the starter order for various compressor motors. In this way, it delivers necessary electrical kick to overcome first inertia so as to synchronize smoothly rotating the compressor; thus saving more electricity while operating smoothly. This relay finds wide application in residential and commercial air-conditioning systems alike refrigeration units.
