ОПИСАНИЕ ПРОДУКТА
ASEA BROWN BOVERI 1SVR427015R0100 - Three-Phase Monitoring Relay
This device is a compact, microprocessor-based three-phase monitoring relay from the CM-PFS product family, engineered for comprehensive supervision of AC mains parameters. It provides critical protection against phase sequence errors, phase loss, phase unbalance, undervoltage, and overvoltage conditions. Designed for integration into industrial control panels, it ensures operational integrity and extends the lifespan of three-phase motors, generators, and sensitive electrical loads in applications such as HVAC systems, pump control, and general machinery protection.
