Product Introduction

This Overvoltage, Undervoltage & Overcurrent Protector provides complete circuit protection for household and industrial use. It monitors voltage and current in real time, cutting off power instantly to shield electrical appliances from damage caused by abnormal voltage and overcurrent.

Built with brand-new relays and all-copper hard connections, it delivers strong conductivity and reliable performance. The device supports automatic reset for hassle-free use. With an exclusive private mold and built-in logo, it combines a stylish look with practical functions, making it a perfect power safety solution.

Product structure and performance characteristics

Voltage Monitoring: Real-time detection of voltage anomalies. If the voltage exceeds or falls below predefined thresholds (e.g., over-voltage: AC270±5V; under-voltage: AC170±5V), the protector instantly cuts off power to prevent damage to connected devices.

Auto-Reclosing Function: Automatically resumes power supply after a brief delay (e.g., 30±10 seconds) when voltage stabilizes, eliminating the need for manual resetting.

Rapid Response: Acts within ≤1 second to safeguard sensitive electronics (e.g., TVs, refrigerators) from voltage surges or drops.

Durable Design: Built with magnetically held relays and micro-processor technology for low power consumption (≤2W) and high mechanical longevity (≥100,000 cycles).

Wide Application: Ideal for single-phase AC 230V systems commonly used in homes and commercial settings, with a load capacity of up to 40A,63A,80A,100A.
