Over And Under Voltage Protector

Dual-row Display Overvoltage and Undervoltage Protector DIN Rail

Product Introduction

This self-recovery overvoltage and undervoltage protector is designed for installation in standard distribution boxes with 35mm DIN rail mounting. It features a dual digital display to monitor real-time voltage and current, providing basic electrical parameter monitoring for circuit protection applications.

The device supports adjustable overvoltage, undervoltage, and overcurrent protection parameters. When abnormal voltage or overload occurs, it automatically cuts off the power supply to protect electrical equipment from damage. Once the grid returns to normal, it will automatically restore power after a preset delay, without manual reset.

With high measurement accuracy, a wide operating temperature range, and multiple current ratings from 15A to 63A, it is suitable for stable and safe power management in residential and commercial electrical systems.

Application Scenarios

1. Residential buildings, rental houses, and family distribution systems
2. Offices, shops, restaurants, and other commercial premises
3. Rural areas and temporary construction power supply with unstable voltage
4. Solar power systems, monitoring equipment, and small industrial control cabinets
5. Warehouses, street lighting control boxes, and various terminal electrical equipment
