Gas discharge tube (GDT) arresters, also known as spark gap devices, are electrical components that limit the voltage applied across their terminals to a safe level. They are widely used in electrical systems to protect sensitive equipment from surges, transients and over voltage conditions. GDTs are used in a variety of applications including power systems, telecommunications, government installations, industrial machinery, and consumer electronics. To meet the demanding requirements of these applications, the design and manufacturing technology of GDTs has evolved significantly over the years.

The CG5150MS is a double port GDT arrester designed to provide surge and transient protection for industrial control systems and other sensitive equipment. Its hermetically-sealed metal-oxidevaristor (MOV) construction and low current let-through characteristics make it ideal for use in applications requiring high-accuracy, repeatable performance with a long life. The CG5150MS is rated for a maximum operating voltage of 380V AC with a breakdown voltage of 675V AC. It has a 250V/ns minimum pulse current margin, a ±20% tolerance from nominal voltage, and the ability to withstand 1 ka8/20μ pre-discharge and 1250V 5kV/2ms impulse.

The CG5150MS’s working principle is based on the electrical property of movs. MOVs have the ability to change their resistance when a voltage is applied, allowing them to limit the voltage and current passing through it. When the voltage exceeds the maximum operating voltage of the MOVs, the resistance suddenly drops, diverting the surge current away from the sensitive load. This is known as a “clamping” action, which effectively reduces the maximum voltage applied to the protected equipment. Additionally, the MOVs act as an absorptive capacitor, dissipating any residual voltage and current which may still pass through the MOVs.

The CG5150MS is ideal for use in industrial control systems, process instrumentation, and other equipment that require extended life, repeatable performance, and robust surge protection. It provides superior protection from both direct and indirect lightning strokes, as well as other types of electrical transients. Its hermetically-sealed construction ensures no air enters its interior, preventing the formation of sweat or condensation which can damage internal components and lead to premature failure.

In addition to its surge protection capabilities, the CG5150MS has a variety of features that make it a particularly attractive choice for a variety of applications. It has an extremelyfast response time, is able to withstand high-current pulses, and is able to maintain its rated maximum operating voltage at a wide range of temperature and humidity conditions. All of these features make it ideally suited for use in environments where dependable, long-lasting performance is required. Whether used for industrial control systems, telecommunications networks, or consumer electronics, the CG5150MS is an excellent choice for those needing a dependable surge protection device.
