The MINILEC VSP D2 is an industrial phase failure relay engineered for reliable protection of three-phase motors, pumps, compressors, and industrial machinery against electrical supply abnormalities. The relay continuously monitors phase sequence, phase failure, and voltage unbalance conditions to prevent motor burnout and equipment damage caused by single phasing or incorrect phase connections. It features adjustable unbalance settings, auto/manual/remote reset functionality, and dual changeover relay outputs for flexible control integration. Designed for DIN rail mounting, the VSP D2 is widely used in industrial automation panels, HVAC systems, pump control panels, cranes, compressors, and process machinery where stable three-phase supply monitoring is critical.
