It’s only a circuit breaker. Thermal Thermal-magnetic Magnetic Yet there is enough com- plexity 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 pro- tected 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 global manufacturer of circuit breakers, E-T-A has selected the 12 most common pitfalls.
