Self-resetting Over/Under Voltage Protector

The 6NTZFS series self-resetting over/under voltage protector is a dedicated device for voltage safety protection of power distribution lines, which can effectively prevent damage to downstream electrical equipment caused by grid voltage fluctuations. Its core functions are as follows: When the grid voltage exceeds the preset overvoltage threshold or falls below the undervoltage threshold, the protector will automatically disconnect the circuit; once the voltage returns to the normal range, it will automatically close and restore power supply without manual reset. The product is equipped with red and green dual-color indicator lights—the red light indicates that it is in over/undervoltage protection state, while the green light indicates normal voltage and unobstructed power supply. The front window integrates a status indication function, allowing users to directly check the device’s operating status without professional tools, thus facilitating daily inspection and troubleshooting.…
