Peco Bimetal Overload Relay PNR-8/10/12 with SPP is engineered to provide advanced thermal overload and Single Phasing Protection (SPP) for three-phase motors operating in heavy-duty industrial and commercial applications. Equipped with a precision bimetal sensing mechanism, this overload relay accurately detects sustained overload conditions and phase failure, automatically disconnecting the motor circuit before overheating or single phasing can cause costly equipment damage. Available with an adjustable relay range from 42–69 A to 270–450 A, it accommodates a wide range of high-capacity motors and demanding operating conditions. Its rugged construction allows seamless integration with compatible contactors, making it ideal for motor starters, pumps, compressors, conveyors, crushers, blowers, HVAC equipment, and other heavy industrial machinery. Designed for reliable long-term performance, the Peco Bimetal Overload Relay PNR-8/10/12 with SPP delivers precise tripping characteristics, stable thermal response, and excellent resistance to electrical and mechanical stress. The integrated Single Phasing Protection enhances motor safety by detecting phase imbalance or phase loss, helping prevent motor burnout, reduce maintenance costs, and minimize unplanned downtime. Suitable for manufacturing plants, mining operations, process industries, water treatment facilities, power generation, industrial automation systems, commercial buildings, and electrical control panels, this overload relay provides dependable motor protection, improved operational safety, and extended equipment service life, making it an ideal solution for high-capacity motor control and protection applications.
