How to Choose an Industrial Surge Protector
An industrial surge protector (also called a surge arrester) protects electrical and electronic systems from damage caused by overvoltages. It diverts energy away from sensitive equipment by changing the direction of the current flow. Using the right surge arrester for your application can ensure the best protection. Incompatible devices can damage sensitive equipment and even cause a fire. The best surge arrester for your needs uses multiple stages of protection.
The best industrial surge protection device has several features to protect your equipment from power surges and short circuits. It can be either DIN-rail-mounted or hardwired. Its marking should include the IMAX value, which measures robustness. A higher IMAX value means it is more tolerant of short-circuiting current. In addition, most major SPDs have passed the UL’s 200kA SCCR test. But it is important to note that the IMAX value does not reflect the real surge energy.
An industrial surge protector has three levels of protection. One type blocks higher voltage from reaching the device, while another is designed to shunt it to the ground. The difference in protection between the two types depends on the design of the connected device. Motors are largely immune to the pass-through voltage, while older electronic components can be impacted, reducing their life spans.
Industrial surge protector should be UL-listed to ensure the highest quality protection. This certification shows that the device has been tested and meets Underwriters Laboratories’ standards (UL) standards. While this certification guarantees the device’s quality, it does not guarantee complete safety. For example, it may not be suitable for outdoor applications, where lightning is a major risk.
Another type of surge protection is called a surge suppressor. The surge suppressors pass the electrical current along the outlet, diverting excess voltage to the ground. The surge suppressor has a metal oxide core connected to the hot and neutral wires, preventing the surge from destroying the device. This type of surge protector also protects UPS batteries from overvoltage. The surge suppressor should be tested and installed before the installation of your UPS.
This industrial surge protector has six outlets and a 1200-joules protection rating, sufficient to safely power your electronics. Its 72-inch power cord comes with an integrated cable wrap to minimize the risk of damaging sensitive electronic equipment. Its metal housing suppresses power spikes and protects electronics with sensitive circuits. The 72-inch cord extends enough to reach any electrical outlet.
It is important to remember that surge arresters are not designed to protect from direct lightning strikes. Their primary function is to protect from electrical transients caused by lightning strikes. Lightning strikes result in ground currents passing over buried conductors. A lightning strike also causes an atmospheric EMP, which passes over overhead conductors. A surge arrester can prevent electrification in such a case but will not prevent electrification caused by a direct lightning strike.
Various types of industrial surge protectors are available. Depending on your application, you may need one for your equipment. Some models have a high level of protection, while others have low-level features. Most units feature a power surge suppressor that prevents surges caused by overvoltage or lightning. It is essential to check the specs and features of industrial surge suppressors to make sure you buy the right model. They will protect your equipment from damage due to power spikes and keep it safe from fire.
