Circuit breakers now sport advanced features that include remote control and operational status reporting. Engineers have long considered circuit protection a stable if somewhat unglamorous area.

I continue to be surprised by how many equipment designers are confused by UL circuit protection standards. In trying to meet conflicting standards, engineers may actually decrease the level of ...

This quick reference guide describes TE Circuit Protection’s products for automotive applications. These circuit protection devices help provide protection for overcurrent, overvoltage, and PCB trace ...

Residual current circuit breakers (RCCB) play a narrow but important role in electrical protection. They are frequently specified, often misunderstood, and regularly credited with capabilities they ...

All of this can be accomplished with the use of a SCADA system within the automation process. However, none of these functions are available if the system is not designed with a reliable power source ...

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.

A circuit breaker that trips repeatedly is often assumed to be defective, but that assumption is frequently wrong. Breakers respond to conditions downstream, and replacing one without understanding ...

The electronic content in modern cars has increased tremendously thanks to the demand for in-car entertainment (“infotainment”) systems and features, such as docking for smartphones, USB ports, and ...

If a motor isn't adequately protected, a short circuit will likely result in premature replacement. Then there's the problem of nuisance tripping upon initial start-up because the magnetic setting of ...

Note: This article is based on the 2011 NEC. Article 430 provides the requirements for electric motors while Art. 440 offers amended and additional requirements for hermetic motors, such as those used ...

My introduction to circuit protection came at the tender age of eight. Being a curious lad with an inventive – and apparently self-destructive – bent, I decided to make my mother a lamp. I put a hose ...

[Mark Rehorst] tells us about a tragic incident involving an untimely demise of $200 worth of motor driving hardware, and shares a simple circuit so that we can prevent such tragedies in the future.
