Copeland 940-C411-82 Start Relay

The Copeland 940-C411-82 Start Relay is a crucial component used to facilitate efficient startups of compressors in HVAC systems. The start relay takes a momentary connection of the power supply to the start windings of compressor motors. Having an Ampere rating of 17.8 A pick-up and 14.9 A drop out, this relay is both and strong enough to serve different electrical needs within various HVAC applications. When it comes to operation, the Start Relay gets activated whenever the system voltage reaches 17.8 A pick up thus allowing current flow into the compressor motor as it commences its starter sequence. After the compressor starts, the relay holds that connection until there is a reduction in voltage down to its dropout threshold of 14.9 A.
