Gas Discharge Tube Arresters (GDT) are devices that safeguard power systems against high voltage surges and electrical transients. PMT3(310)15001 is a GDT model that is designed for overvoltage protection of static low-voltage power networks and for use in DC control systems operating up to a maximum of 310 volts. This model has superior transient performance for 120 pulses of up to 6kV and a continuous operating voltage (COV) up to 1.5kV.

The working principle of PMT3(310)15001 GDT arrester is based on the Townsend gas discharge effect. It involves two electrodes (anode and cathode) placed inside a gas filled arrester chamber. When an over-voltage is applied to the device, electrons flowing between the two electrodes cause ionization of the air or gas within the arrester. This forms a conductive path between the electrodes that allows a current to flow, thereby reducing the voltage that is applied to the device. As this current flows through the device, it dissipates energy in the form of light, heat, and sound.

The PMT3(310)15001 GDT arrester is designed to provide over-voltage protection for low-voltage power networks and DC control systems operating up to a maximum of 310 volts. It features a wide range of surge current dissipation and excellent transient performance. The device can withstand up to 6kV pulses of 120 pulses and continuous operating voltage (COV) up to 1.5kV. It is also designed for long-term operation in the harshest environments as it has IP67-rated protection against dust and weather.

The PMT3(310)15001 GDT arrester is designed to provide reliable protection to static low voltage power networks and DC control systems. It is an ideal solution for modern power utility applications where over-voltage protection is critical. It is suitable for long-term operation in harsh environments and offers superior transient performance for up to 6kV pulses and a continuously operating voltage (COV) up to 1.5kV.
