When V-Blox Corporation began researching the availability of enclosures to house their control systems, they knew a key requirement was the ability to pass UL fault current testing. Find out why they chose Stahlin Non-Metallic Enclosures for their application in Stahlin Non-Metallic Enclosure Control Systems Application Case Study.
Lightning is a capricious, random and unpredictable natural event. When lightning strikes a power line it can travel along the line and enter a building’s wiring system, causing a power surge. Damage from electrical transients, or surges such as lightning, is one of the leading causes of electrical equipment failure. Electrical transients are short duration, high-energy impulses imparted on the normal electrical power system whenever there is a sudden change in the electrical circuit.
Surges can also come from normal utility switching operations, or unintentional grounding of electrical conductors (such as when an overhead power line falls to the ground). Surges may even come from within a building or facility from fax machines, copiers, air conditioners, elevators, motors/ pumps, or arc welders, to name a few. In each case, the normal electric circuit is suddenly exposed to a large dose of energy that can adversely affect the equipment being supplied power. The National Lightning Safety Institute estimates on an annual basis lightning causes more than 26,000 fires in the United States, with damage to property in excess of $5-6 billion.
Replacing buildings and equipment, as well as repairing disruptions to business operations, incurs considerable expense. Fortunately, most losses caused by lightning strikes can be prevented by installing proper lightning protection systems. Surge protection properly sized and installed is highly successful in preventing equipment damage, especially for sensitive electronic equipment found in most equipment today. All V-Blox panel mounted lightning and surge protection products not only stop surges and lightning from doing damage to downstream electrical equipment, they are also warranted for 15 years with a guarantee for repair or replace of any damaged equipment up to…>>Read More
