OBS7-6-VA/3P+N/63A

Three Phase Digital Voltage/Current Protector with Lighting Logo

This three-phase over & under voltage protector adopts a brand-new mold design and is made of high-performance PA66 material for its outer shell, featuring excellent durability. It supports built-in logo display on the internal screen, with reliable and superior quality. This versatile protector is suitable for both household and industrial applications, and is available in 63A,80A and 100A current specifications to meet diverse power safety protection needs.
Product Introduction

Once the voltage reverts to a normal range, it restores power without human intervention—ensuring non-stop protection for electrical equipment and enhancing user safety. What’s more, this latest model supports custom logo integration on its display screen , adding a personalized touch for branding needs.

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.
