Copeland 940-0135-00 Current Sensing Relay

The Copeland 940-0135-00 Current Sensing Relay is an essential part of HVAC systems, which is used for controlling electrical currents efficiently. This relay works by measuring the current passing through a circuit and switching on or off other appliances depending on the set currents. It is commonly used in HVAC equipment like compressor, blower and electronic air cleaner to make sure that these equipment work at safe current levels. The advantages of this relay include shielding of overcurrent conditions which is dangerous to most equipment and the ability to improve system dependability by isolating equipment that has abnormal current levels.
