GTCA28-471L-P05

Gas Discharge Tube Arresters (GDT) are devices which, under normal conditions, provide low resistance path for surge currents while isolating the connected equipment from the surge. The GTCA28-471L-P05 is one such device and is designed to protect electrical systems or components from transients due to atmospheric or switching surges. It is available in a wide range of power ratings, clamping voltages,capacitance values, series inductances (maximum allowable surge) and various other parameters.

The primary purpose of the GTCA28-471L-P05 is protection of high-voltage equipment from transient overvoltage. When an overvoltage surge occurs due to a short circuit or other reason, the GTCA28-471L-P05 provides a low resistance path for the surge current to travel, thus limiting the voltage that reaches the protected equipment. When the peak voltage of the surge exceeds the nominal breakover voltage of the arrestor, the tube begins conducting and diverting the surge current away from the protected equipment. After the current reaches its peak, the GTCA28-471L-P05 quickly returns to a high-resistance state, ensuring that only the intended current is allowed to reach the protected equipment.

Apart from protecting electrical systems and components from transients, the GTCA28-471L-P05 also helps to maintain long-term reliability of the system. The device is designed to remain in an insulating, non-conducting state during normal operating conditions, effectively isolating the protected system from external influences. This makes the GTCA28-471L-P05 suitable for applications where frequent service interruptions due to power surges are undesirable, such as in telecommunications systems. Additionally, the device also reduces power dissipation, as it does not require any additional energy to remain in the non-conductive state.

The GTCA28-471L-P05 also finds applications in audio-visual equipment, industrial machinery, lighting systems and medical equipment. In all of these applications, it is typically used in combination with other surge protection devices such as metal oxide varistors (MOVs) or autotransformers. Additionally, the GTCA28-471L-P05 can also be used in conjunction with Parallelplate Spark Gap Arrestors to provide complete transient protection solution.

In conclusion, the GTCA28-471L-P05 is a versatile surge protection device that can be used in a wide range of applications. It provides reliable protection from transient overvoltages and also helps to maintain long-term reliability of the system. Additionally, it is typically used in combination with other surge protection devices to ensure complete transient protection.
