GT-CM230L

Gas Discharge Tube Arresters (GDTs) are an important electrical component used to protect against transient overvoltages. The most common type of GDT is called the GT-CM230L, which is a low-voltage, low-capacity arrester with a break-over voltage (BOV) rating of 230V. In this article, we will look at the application field and working principle of the GT-CM230L.

GT-CM230L is a great option for installations in residential, commercial, and industrial applications. It is primarily used to protect circuits from short-term overvoltage events, such as lightning strikes or switching surges. The GT-CM230L features a low capacitance rating, which means it is more effective at dealing with short-term transients, as opposed to sustained overvoltages. It is also built using high-quality components and is therefore very reliable and long-lasting.

The GT-CM230L is designed to work in conjunction with surge protective devices (SPDs), which are used to protect against sustained overvoltages. The SPD is designed to reduce the incoming voltage by diverting it away from the protected circuit. The GT-CM230L is then connected in parallel with the SPD in order to protect against transient surges in voltage, current, or frequency. The GT-CM230L will break over when the voltage exceeds 230V, diverting the surge away from the circuit.

The GT-CM230L is a glass-encapsulated gas discharge tube arrester which contains two metal electrodes, which are enclosed in a glass tube and spaced at a specific distance from each other. When a voltage surge occurs, the glass tube will ionize and create a plasma channel. This channel allows the surge to be diverted away from the circuit, preventing damage to the sensitive electronics in the device.

The GT-CM230L is also equipped with a thermal cut-off feature, which will automatically disconnect the arrester in the event of an overload. This helps to protect the arrester from any damage in the event of repeated surges.

The GT-CM230L is a reliable and cost-effective arrester that can help to protect against transient overvoltages. It is a simple device with few moving parts, making it maintenance free. It is also very compact in size and requires no special installation or additional hardware. Due to its low-cost, low-maintenance design, it is a popular choice for applications where both cost and space are limited.

In conclusion, the GT-CM230L is an effective and reliable low-voltage arrester that can be used in both residential and commercial installations. It is very compact and easy to install, and requires almost no maintenance. It is an affordable solution for protecting against transient overvoltages, and can be used in conjunction with surge protective devices for added protection.
