Gas Discharge Tube Arresters (GDT) are commonly used for protecting electrical and communication circuits against transients such as lightning strikes. They work by providing a short circuit between the circuit and ground in the event of large voltage spikes on the line. The GTCA28-272L-P03 is a type of GDT specifically designed for broadband power line over-voltage protection.

The GTCA28-272L-P03 is constructed of two concentric cylinders of silica sand and a gas-filled cavity in the center. It acts as a spark gap between the two cylinders. When a transient over-voltage occurs, the gas in the cavity ionizes and produces an electrical arc across the spark gap, providing the short circuit necessary to protect the circuit. The GTCA28-272L-P03 has a wide frequency range of 10MHz to 720MHz, and can handle over-voltage transients up to 4kV.

The GTCA28-272L-P03 is used in a variety of applications, such as in over-voltage protection for low voltage and medium voltage power distribution, telecommunications, and data communication systems. In these applications, the GTCA28-272L-P03 is typically installed between the incoming lines and the protected equipment. It provides a low impedance short circuit path for the over-voltage transient to ground, thereby protecting the equipment from damage.

In addition to protecting the equipment, the GTCA28-272L-P03 also provides protection from false triggers. It contains an internal current limiting element that prevents excessive current from flowing during an over-voltage event, thus protecting connected circuits from damage. It also contains a thermal fuse that will open the circuit if temperatures exceed certain limits, ensuring the end user will not be exposed to hazardous voltages.

The GTCA28-272L-P03 is easy to install and maintain, and is rated to last for many years. It is manufactured to the highest quality standards and is designed to withstand environmental conditions such as vibration, humidity, temperature, and corrosive gases. It is also RoHS compliant and UL certified, thus making it a reliable choice for over-voltage protection.

In summary, the GTCA28-272L-P03 is a type of Gas Discharge Tube Arrester specifically designed for broadband power line over-voltage protection. It is constructed of two concentric cylinders of silica sand and a gas-filled cavity in the center which acts as a spark gap in the event of large voltage spikes. The GTCA28-272L-P03 is typically installed in various applications to protect equipment from over-voltage transients, and also contains elements to prevent false triggers and excessive current. It is easy to install and maintain, and is designed to last for many years. It is also RoHS compliant and UL certified. This makes the GTCA28-272L-P03 a reliable choice for over-voltage protection.
