It's only 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. Underprotected circuits leave equipment vulnerable to damaging electrical surges. Overprotected 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”. As a leading manufacturer of circuit breakers for equipment for over 50 years, E-T-A has helped countless engineers navigate the specification process. While speaking to design engineers, E-T-A’s applications engineers have encountered many misconceptions, and 12 of them have been selected to focus on in this product training module.
