Dual-Display Auto-Reset Voltage Current Protector

This automatic reclosing protector measures 85 × 36.5 × 65.5 mm and weighs 140 g, constructed from durable plastic housing. It operates at 230 V AC with selectable rated current options of 40 A or 63 A. The device features dual digital LCD screens that simultaneously display real-time voltage and current values using large, clear fonts. Protection thresholds include overvoltage (adjustable between 230–280 V) and overcurrent — both user-customisable via built-in intelligent chips. When overvoltage, undervoltage or overcurrent is detected, it instantly cuts off power to safeguard connected appliances; once the fault clears, it automatically recloses to restore supply without manual intervention. Designed for DIN rail mounting or wall installation, it requires no screws and fits compactly in standard distribution boards. Its large wiring ports simplify electrical connections. Ideal for rental properties, schools, shopping malls, factories and other commercial or residential settings — especially when protecting high-power appliances such as electric heaters, ovens, water heaters, refrigerators and air conditioners.
