Copeland 940-0001-79 Potential Relay

The Copeland 940-0001-79 Potential Relay is an electric potential management and monitoring device of HVAC systems is essentially built around. It measures only 3.5”-by-2.7”-by-2.2”, but its abilities are awesome thus effecting the function excellently. In order for this relay to work, it needs power supply at 400VAC. The way this works is by monitoring voltage supplied to motor or compressor of HVAC system, so that it remains within designed limits. When there is any deviation from desired levels, the relay activates either to protect the equipment or signal malfunctioning in the operation regardless of preserving an efficient system in order to avoid any possible electrical imbalance damage during operation. All in all, this potential relay is designed to be used along with Copeland compressors and other HVAC equipment.
