Manufacturers of circuit-protection devices have significantly improved the performance of their safety components to protect electronic devices and equipment from a range of failures caused by ...

Most surge protectors fail quietly. They don’t spark, smoke, or give you any dramatic warning. They simply stop protecting your devices – and you’d never know it. Nearly every home today has ...

The rate of transient occurrences varies with every power system. Recent studies show that surges of 1kV or less are common — whereas 3kV surges are rare. Protecting against more frequent (internally ...

Why a gas-discharge tube is an important component for overvoltage protection. The history of spark gaps—predecessors to GDTs—includes a role in famous movies. How a new, compact, surface-mount GDT ...

With the 2020 revision of the NEC, Art. 242 replaced two individual Articles that appeared in earlier editions of the Code — Art. 280 [Surge Arrestors] and Art. 285 [Transient Voltage Surge ...

Circuit protection devices are safety components that are used in every electronic device and system, ranging from the smallest smartphones and wearables to high-reliability applications like ...

Barring something like an incorrect transformer tap connection, an overvoltage is a momentary event in which voltage “surges” beyond nominal. We often call that a transient. A breaker or fuse is ...
