Gas Discharge Tube Arresters (GDT) are a form of static current-limiting device composed of a series of high-resistance components that block the uncontrolled flow of current. AG20PC152F-L3N is an example of a Gas Discharge Tube Arrester (GDT) designed for use in industrial control equipment, typically in industrial equipment operated in hazardous environments such as in explosion-proof enclosures and hazardous area equipment.

True to its name, the AG20PC152F-L3N works by using a series of low-resistance segments of wire to create an open-circuit when the limited current-limiting current is encountered. During normal operation, the current flows through the arrester and is limited by the voltage drop across it. When the limited current limit is reached, the arrester will open-circuit, preventing any further current flow. The operating current is user adjustable on AG20PC152F-L3N with a variable resistor inside the arrester.

AG20PC152F-L3N is designed to protect high voltage or low voltage medical equipment, mining equipment, power supplies, pumps, motors and more. It also includes several safety features, including reverse-polarity protection and fault detection. The fault detection feature allows the device to sense under-voltage and over-voltage conditions and shut off power before damage occurs.

When considering the application of AG20PC152F-L3N, it is important to consider the environment in which it will operate. To ensure that the arrester performs as intended, it should be used in a temperature range of -5°C to +55°C (23°F to 131°F). Additionally, given that the arrester is designed to protect critical components, it should be installed away from sources of excessive noise and electromagnetic interference.

When properly installed, AG20PC152F-L3N provides reliable protection against transient overvoltage conditions. The arrester is UL recognized for use in hazardous locations and is suitable for medical equipment, high voltage power supplies, automotive, mining equipment, pumps, and other industrial equipment.

Gas Discharge Tube Arresters (GDTs) like AG20PC152F-L3N are designed to protect equipment from currents of different origins, whether they be from a surge, interference, or power source, by providing an open path for the current to bypass. The GDT consists of several concentric anodes and cathodes that create a field, forcing electrons and ions to move along the arrester’s surface when an over-voltage is encountered. When the voltage exceeds the arrester’s limiting current, a spark appears and the arrester opens, preventing any further current flow. The operating current is adjustable with the variable resistor inside the arrester. This allows the AG20PC152F-L3N to be used in a wide variety of applications.
