Gas Discharge Tube Arresters (GDT)

Gas discharge tube arresters (GDT)are protective devices for electrical circuits that are designed to suppress transient strikes of lightning and other overvoltage events. The GDT uses two ports with an internal gap filled with a gas, usually a noble gas or a non-reactive gas. A 2057-40-BT1LF GDT is designed to protect electronic components, machines, and personnel from damage caused by overvoltage events by temporarily diverting the power surge to a grounded conductor.When an overvoltage event occurs, the GDT acts like a damper, limiting the overvoltage. A voltage spike, on the other hand, is an instantaneous surge in electrical current caused by lightning storms, electrical surges or other disturbances, often referred to as an electrostatic discharge. Voltage spikes are prevented from damaging the system by the GDTs opening and instantly blocking the voltage spike.GDTs consist of two main components: a dielectric material that is surrounded by a metal electrode. The electrode is the portion of the GDT that is exposed to an overvoltage event, and it is designed to provide a path for the transient current surge to travel to ground. The dielectric material is electrically insulating, and its purpose is to keep the two electrodes apart until the voltage reaches a certain level, at which point the dielectric material breaks down and allows current to transfer through the GDT.The 2057-40-BT1LF GDT has been subjected to the highest international testing standards, making it one of the safest and most reliable GDTs available. Its high-quality design includes an isolated lid, a snap-off lid, and a built-in fuse protection mechanism that helps to protect against overvoltage spikes and other electrical disturbances. In addition, the 2057-40-BT1LF GDT features an easy-to-install enclosure that keeps it safe from external sources of interference.The 2057-40-BT1LF GDT is typically used in industrial and commercial applications where critical equipment is powered and protected. Its high-quality design and superior performance make it ideal for a wide range of applications such as: telecom equipment, automotive electronics, test and measurement equipment, industrial machinery, medical equipment, and HVAC systems.In summary, the 2057-40-BT1LF GDT is a reliable and effective way to protect electrical circuits from damage caused by overvoltage events. Its high-quality construction and robust design make it one of the safest and most reliable GDTs on the market. Its easy-to-install enclosure makes it suitable for a wide range of applications in various industries, making it an ideal choice for protecting your electrical system.
