Fuse vs. circuit breaker: How to choose the right device for your application
Is a fuse or circuit breaker best for your design? Here are some pointers to help you decide. Three main factors go into choosing between circuit breakers and fuses: Convenience for the user, cost, and degree of protection. This white paper will give you guidance on what circuit protection device is best for your equipment.
12 Most Common Mistakes When 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".
