Description
The Schneider Electric (Square D) CA2SKE20U7 is a 240V, 10A alternating relay engineered to provide automatic load rotation in HVAC and building automation applications. By alternating operation between two loads — such as pumps, compressors, or fans — this relay promotes equal run-time distribution, reduces wear on individual components, and extends overall system life.
Designed for demanding commercial and industrial environments, the CA2SKE20U7 delivers dependable switching performance in hydronic systems, chiller plants, boiler rooms, and other dual-pump or dual-motor configurations where balanced operation is critical.
