CNC EL240333 Voltage and Current Control Relay, 63A, 3-Phase, DIN Rail Mount, Adjustable Protection

Three-phase voltage and current control relay engineered for robust protection of motors and electrical equipment. This 63A monitoring device continuously checks over/under voltage, over/under current, phase sequence, phase loss, and phase imbalance, ensuring reliable operation in industrial and commercial installations.

Advantages

Comprehensive protection in a single unit: the relay monitors all critical electrical parameters on each phase independently. Adjustable trip thresholds and delay times allow precise adaptation to your application, preventing nuisance tripping and equipment damage. The clear LCD display provides real-time readings and fault indication, simplifying commissioning and diagnostics. DIN rail mounting enables fast installation in standard distribution boards.

Suitable for

• Three-phase motor protection in pumps, compressors, conveyors, and HVAC systems
