The TOMZN TOVPD1-63VAE 3-IN-1 Voltage Protector is multi-function DIN-rail mounted protection relay designed to safeguard electrical circuits and appliances from voltage and current abnormalities. It provides adjustable over-voltage, under-voltage, and over-current protection, cutting off power when values exceed preset safe limits and automatically restoring supply once normal conditions return. The unit also features real-time digital displays for voltage, current, and energy (kWh), and retains fault/energy data after power loss. With configurable delay and recovery settings, this protector is ideal for homes, commercial panels, and industrial electrical systems where reliable protection and monitoring are needed.
