Product Introduction

The TOVPD1-63DK is an intelligent protector that integrates over-voltage, under-voltage, and over-current protection into a single compact unit. When a fault occurs, it simultaneously disconnects both the live (L) and neutral (N) wires, ensuring complete isolation and enhanced safety for connected electrical equipment. All protection thresholds are user-adjustable, allowing customization to match local grid conditions. The device features real-time voltage and current display, voltage calibration (±9.5% adjustable), automatic recovery after fault clearance, fault inquiry, and factory reset functionality. Designed for 35mm DIN rail mounting, the TOVPD1-63DK delivers reliable, flexible, and intelligent protection for residential and commercial electrical installations.
