Contactor-Based Heavy-Duty Protection : This is a contactor-driven protection relay, designed to control external contactors for handling high-load industrial equipment. Unlike small inbuilt relay-type protectors, this system is safer and more reliable for motors, compressors, and heavy machinery.

3-Phase Fault Protection: Multi-functional and intelligent protection device. A 3-phase relay protector that is equipped with many intelligent protections i.e overvoltage, undervoltage, unbalance voltage, staggered phase protection.

Adjustable Protection Settings: Adjustable overvoltage value (390-490V), undervoltage value (300-370 V), voltage imbalance range(5%-29%) and action time (0.1-25s).

LCD Display with Live Monitoring: Clear LCD screen shows real-time voltage readings, fault status, and parameter settings — making it easier to diagnose issues.

Wide Industrial & Commercial Applications: Ideal for protecting three-phase motors, compressors, pump panels, HVAC systems, elevators, CNC machines, and heavy industrial equipment. Perfect for factories, commercial buildings, workshops, and distribution panels where stable voltage and phase protection are critical.

Description

Protect your 3-phase equipment from voltage instability with this intelligent multi-functional protection relay. It offers complete protection against over-voltage, under-voltage, phase loss, phase sequence errors, and voltage imbalance, ensuring your machinery and appliances stay safe from electrical faults.

The LCD display clearly shows real-time voltage readings, fault status, and settings, making monitoring easy and convenient. You can adjust the over-voltage (390–490V), under-voltage (300–370V), voltage imbalance (5–29%), and response time (0.1–25s) to match your specific needs.

Easy to install on a 35mm DIN rail, this durable and smart protector is ideal for use in factories, workshops, and industrial setups where stable 3-phase operation is essential.
