Dirty Dozen: The 12 Most Common Mistakes of Specifying Circuit Protection for Equipment

It's only a circuit breaker. Yet there is enough complexity and confusion when it comes to specifying circuit protection that many engineers are designing equipment with too little or too much protection. Under protected circuits leave equipment vulnerable to damaging electrical surges. Over protected circuits add cost and can lead to nuisance tripping. Like Goldilocks and the three bears, the goal is to specify circuit protection that is "just right"...

Improve Plant Production by Addressing 24VDC Switch-Mode Power Supply Issues

For most industries, the accepted norm for unplanned downtime is 5% of operating time, which represents a direct, significant loss of revenue and therefore profit. But have you ever stopped to consider the true cost of downtime? Read the latest white paper from E-T-A to see how the integration of electronic circuit control technology can reduce the downtime of your 24VDC system designs...

Overload or Short Circuit Protection? How to Protect your Design Against Both Dangers

Circuit breakers are used in a variety of ways. They are mounted in panelboards to protect branch circuit wiring, and they are built into equipment to protect it. With this range of applications, it's not surprising that a circuit breaker must provide both short circuits and overload protection. This white paper will give pointers on how to determine the main job a breaker must do and how to make an appropriate selection...
