Copeland 940-0090-06 Current Relay

The Copeland 940-0090-06 Current Relay in compressor safeguards for HVAC systems cannot be overstated. Its switch-like function is to continuously check the amount of electricity being supplied to the compressor motor. If the electrical current surpasses a particular limit set beforehand, the relay is meant to break the circuit. In this case, as the current ramps up, it will only switch on when it has reached a certain value which is called pick-up. The relay allows current flow when it falls within an acceptable range. Surge or overload conditions will cause relay devices to open and disrupt power supply before any damage occurs normally hence effectively performing its duties within specified temperatures in Fahrenheit including 32 and 140 degrees Fahrenheit; thus making it appropriate for most commercial air conditioning sectors and family residences.
