Description
The Copeland 940-0163-17 Current Relay is a crucial element of HVAC systems that are meant to safeguard compressors against the effects of too much electrical current. It requires a power supply of 240 VAC, which makes it portable and easy installation. This current relay works by monitoring electrical currents in motors powering compressors. When the magnitude exceeds a certain predetermined measure, the relay opens up thereby preventing any further rotations by way shutting down power thus averting damage to the compressor as well as also periodical repair costs since other initial parts deviate within time-frame like capacitors would always be replaced during maintenance programs thus standardizing their performance, thus it is not durable. Instead, such situation prolongs its life time. Usually, it finds its application in air conditioning and refrigeration systems for protecting them from over-currents while increasing their longevity.
