Adjustable Voltage Protector 110V, Auto‑Reset 1‑63A Smart Circuit Breaker

1.Designed to help protect electrical circuits from unstable power conditions, this adjustable voltage protector automatically monitors voltage and current in real time and disconnects power when abnormal levels are detected. The built-in protection system helps reduce the risk of damage to appliances, motors, and control equipment caused by overvoltage, undervoltage, or overcurrent situations. 2.The protector features an automatic trip and smart reconnect function that cuts off the circuit during abnormal conditions and restores power once the voltage and current return to a safe range. This automatic recovery design helps maintain continuous operation without the need for manual reset, making it suitable for both home and industrial electrical systems. 3.Front panel buttons allow users to adjust protection parameters such as overvoltage, undervoltage, overcurrent limits, and recovery delay time. The flexible settings make it easier to adapt the device to different electrical loads, appliances, and installation environments without complicated configuration. 4.A clear LED digital display provides real-time monitoring of voltage, current, and frequency levels. Multiple display modes allow users to quickly check electrical conditions and identify abnormal fluctuations, improving convenience during installation, inspection, and maintenance. 5.Designed for standard 35mm DIN rail installation, this voltage protection relay fits neatly inside distribution boxes and electrical control cabinets. It can be used in residential circuits, lighting systems, motors, industrial control equipment, and other electrical applications that require stable voltage and reliable protection.
