Over And Under Voltage Protector

Triple-row Display Overvoltage and Undervoltage Protector DIN Rail Mounted

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 triple digital display to monitor real-time voltage, current, and power consumption, providing enhanced electrical parameter visibility for energy management and system protection.

The device supports configurable overvoltage, undervoltage, overcurrent, and power protection settings. When abnormal voltage, current, or load conditions occur, it automatically disconnects the circuit to protect connected electrical equipment. Once the power supply returns to normal, the device will automatically restore power after a preset delay, without requiring manual reset.

Available in multiple current ratings from 15A to 63A, it offers high measurement accuracy, wide operating temperature adaptability, and stable performance for electrical protection and energy monitoring applications.

Application Scenarios

1. Residential buildings, apartments, and home distribution systems
2. Offices, retail stores, restaurants, and commercial facilities
3. Rural areas and construction sites with unstable voltage supply
4. Solar power systems, energy monitoring systems, and industrial control cabinets
5. Street lighting systems, warehouses, and terminal electrical equipment
