Gas Discharge Tube Arresters (GDT) are devices used to protect electrical systems and circuits from power surge damage. The principle behind GDT protection is to create a spark gap in an electrical circuit that diverts high voltage surge current safely away from the system or circuit. They are also known as spark gap arresters, since they work to stop the passage of excessive energy into the system or circuit.

The 2036-30-SMLF gas discharge tube arrester is an industrial grade type 2 surge protective device designed for low frequency lines. This arrester is designed to feature a spark gap variety so that four high stepping power surges can be safely diverted away from the system or circuit.

The 2036-30-SMLF is constructed with a hard epoxy non-metallic shell and solid insulated casing, which is then filled with a polyurethane foam that is capable of absorbing shock and spread the heat generated from the arrester. The spark gap is a permanently factory-located, sealed cavity in the arrester and is housed between two electrodes which are connected and enclosed by an aluminum tube. The gap is constructed to have two “bleeder resistors” (resistive network) in order to reduce the surge energy. As mentioned, the gap is sealed so that no air can escape or moisture can enter.

The 2036-30-SMLF gas discharge tube arrester’s working principle is an integral part of the device. A diode is used to ensure that the gap is left open at all times (unless a surge occurs). When a surge is present, the large current flow causes the dielectric strength of the air in the gap to decrease, this decreases the breakdown voltage. As a result, the ionization of the air occurs and creates an arc, diverting the electrical surge away from the system.

The arrester is suitable for a variety of applications such as power supplies, industrial plants, broadcast systems and automotive industries. This arrester provides protection against primary lightning and surges for typical loads such as electronic motor drives, programmable logic controllers, microprocessors, microcomputers and more. The 2036-30-SMLF arrester\'s sophisticated diode design reduces the effects of power transients and thus increases the device’s life expectancy.

To summarize, GDTs are surge protection devices designed to divert current caused by high voltage power surges. In particular, the 2036-30-SMLF gas discharge tube arrester is an industrial grade type 2 surge protection device designed for low frequency lines. It features a spark gap variety and is constructed with a complex diode system. This arrester is suitable for a variety of applications and provides protection against primary lightning and surges for loads such as electronic motor drives and microprocessors.
