Copeland 971-0090-47 Overload Relay

The Copeland 971-0090-47 Overload Relay is a part of HVAC systems that was made to guard the compressors and different electrical appliances. While it has input voltage of 24V, this relay works with Amperes between 12A and 15A and can be used in single-phase applications. It possesses manual changeover which facilitates resetting and adjusting with ease. This device operates at temperatures ranging from -4°F to 140°F, thus ensures dependability under different weather patterns making it a perfect option for confined spaces within HVAC systems. It prevents possible overloads by checking current flow and temperature around the compressor before cutting off power supply to save it from damage.
