Gas Discharge Tube Arresters (GDT) are safety devices that are commonly used in electronic circuits to provide protection against temporary overvoltages. The 2026-40-C13F arrester is one particular type of GDT that is designed to be installed in residential and commercial areas. In this article, the application field and working principle of the 2026-40-C13F arrester will be explained.

Application Field

The 2026-40-C13F arrester is a metal oxide varistor (MOV) type of GDT with an operating voltage of 135 VAC and a current rating of 6.5 kA. Its metal oxide-filled core is encapsulated in an ABS plastic housing for mechanical and electrical protection. It is suitable for a variety of residential and commercial applications, including protection against transient overvoltages from lightning strikes or nearby power system events. It is the most popular GDT used in residential and commercial settings due to its relatively low cost and reliability.

Working Principle

When connected in series with the protected load, the 2026-40-C13F arrester works by limiting the voltage and current that passes to the load. During normal operating conditions, the arrester is in an open state, allowing normal current to pass through to the load. However, when its threshold voltage is exceeded by a surge or lightning strike, the arrester begins to conduct current by rapidly discharging a surge into the earth ground. This discharge of current prevents the transient voltage from exceeding its threshold, thereby protecting the connected load.

The 2026-40-C13F arrester has two additional characteristics that improve its ability to provide protection against overvoltages. The first is its ability to self-restore after a surge event. The arrester’s MOV core is capable of quickly dissipating any residual energy from a surge, allowing it to quickly reset and be ready for the next surge event. The second characteristic is its low residual voltage after a transient event. After the surge dissipates, the arrester’s residual voltage is significantly lower than the original transient voltage, thus preventing long-term damage to the protected load.

The 2026-40-C13F arrester provides reliable protection against transient overvoltages in residential and commercial settings. Its combination of low cost, reliable performance, and easy installation make it an ideal solution for protecting electronic circuits from damaging overvoltage events.
