This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

Understanding the role of short-circuit current is critical to the reliability of your electrical system and to the safety of the people who maintain it. When designing or modifying a distribution ...

The increasing use of integrated circuits in modern electronic systems has resulted in a growing awareness about lightning overvoltage hazard. The integrated circuits, especially large-scale ...

Protecting a power supply and its load from each other’s faults requires components and functions such as the fuse, undervoltage lockout, crowbars, and clamps. Power protection is like insurance: You ...

Advancements in power TVS diodes have made them an effective alternative to metal oxide varistors (MOVs) in protecting AC and DC power supplies from power line surges and indirect lightning strikes.

This article presents an overview of circuit protection technology used for automotive applications. It briefly describes ESD protection, load dump protection, as well as short circuit (application ...

This flexibility allows installers and designers to match breaker characteristics precisely to system requirements, improving selectivity and operational reliability. These devices combine thermal and ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Now that autos are moving toward high-powered battery voltage, the industry is turning new attention toward making sure the flow can stop on a dime when needed. Power management company Eaton Corp.
