Gas Discharge Tube Arresters (GDT) are a type of surge protection device. They are used in a wide range of electrical and electronic applications, from industrial equipment to consumer electronics. The GTCA28-900M-R10 is a 36.4mm x 93.6mm mounted variable spacial gas discharge tube arrester that provides protection to direct current applications.

The GTCA28-900M-R10 is commonly applied to systems found in many sectors that run on direct current such as: Line switches, uninterruptible power supplies (UPS), inverters, data processing equipment, optical communication systems, telecommunication systems, DC power sets, rectifier/generator systems, surge suppressors, and many more.

The GTCA28-900M-R10 arrester is designed to protect against transient overvoltage such as those caused by lightning and other surge events. It works by providing a low-impedance path for the surge current, thus providing a rapid response which prevents excessive surges from damaging the equipment connected to the system.

The arrester is composed of several elements which include a spark gap, dielectric material, and a spark gap cover. These elements are arranged in a specific configuration that determines the amount of protection it offers when exposed to a surge.

When an overvoltage condition occurs, the spark gap of the arrester is the first to respond. The spark gap provides a direct path for the overcurrent or surge, thus preventing large spikes from damaging the equipment or system it is intended to protect. The dielectric material is also activated to channel the surge away from the equipment before it can reach the spark gap cover. The dielectric material absorbs the energy of incoming surges and dissipates it as heat, limiting the damage that the surge can cause. Finally, the spark gap cover provides a final barrier against the surge, preventing any further damage.

The GTCA28-900M-R10 arrester is rated for a maximum surge current of 200A, a maximum voltage of 900V DC, and an excellent surge impulse life of 10 times. It also offers high energy absorption and low varistor voltage levels, providing superior protection for sensitive electrical and electronic components.

The installation of GTCA28-900M-R10 arresters should always be undertaken by a qualified and experienced electrician. The arresters should be securely mounted, preferably at the system input or a grounded circuit point. It is important to ensure that the arrester is correctly wired to the system and that all electrical connections are tight and properly insulated.

In summary, the GTCA28-900M-R10 arrester is a reliable and affordable solution for providing surge protection in direct current applications. Its robust design ensures maximum protection to the equipment or system, while its easy installation and maintenance make it an economical choice.
