Product Introduction

When the voltage gets back to a normal state, the device resumes power on its own—no manual operation is required. This ensures household appliances are protected continuously and user safety is boosted.

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 63A.
