2046-40-C2LF

Gas Discharge Tube Arresters (GDT) are devices used in electrical systems to limit or stop the flow of current. They are typically used for overvoltage protection, supplementing or replacing fuses in those applications. The 2046-40-C2LF is an anode-type GDT suitable for pulse protection with a rated impulse current of 40 kA (8/20 μs).

The 2046-40-C2LF is a 25mm (1in) GDT made with an electrolyte-filled glass-ceramic material, which contains ceramic granules and synthesized electrolyte particles suspended in epoxy resin. The two electrodes of a GDT are known as the ‘cathode’ and the ‘anode’. The main function of the cathode is to provide a path for the current to immediately short-circuit during an overload. The anode on the other hand, takes the path of the higher current in order to dissipate it safely. The 2046-40-C2LF utilizes anode-type arrester technology and is designed with an anode contact that can rapidly dissipate large currents.

The 2046-40-C2LF is designed to be placed between the utility power line and the protected circuit. During an overvoltage condition, the current is shorted to ground by means of the cathode contact, while the anode contact absorbs and dissipates the energy generated by the overvoltage. The anode contact is designed to limit the voltage level of the protected circuit to a safe level, and the cathode contact absorbs and dissipates the energy generated during the short-circuiting of the overvoltage. The 2046-40-C2LF is designed to protect against electrical surges and high-energy pulses, such as those generated from lightning strikes.

The 2046-40-C2LF is an anode-type GDT with two small, internal resistors that can be used to control the voltage level by providing a low impedance path that limits current flow. The two resistors are one of the GDT components that allow the unit to react quickly to changes in the line voltage. This helps to reduce the duration and impact of destructive electrical events such as lightning surges and spikes. As the overvoltage rises above the rated voltage of the GDT, the resistors rapidly draw current away from the protected circuit and dissipate it through the GDT anode terminal.

In conclusion, the 2046-40-C2LF is a Gas Discharge Tube Arrestor that is designed to limit the flow of current during an overvoltage or surge condition. Its unique design allows it to rapidly react to changes in line voltage and to provide a low impedance path that limits current flow. This helps to reduce the duration and impact of dangerous electrical events and to protect the connected circuits from overvoltage damage.
