Choosing the right circuit breaker

摘要

Any electrical or electronic product that is designed with inadequate circuit protection or without any circuit protection at all is an accident waiting to happen. Protecting your valuable equipment means guarding the entire electrical system―including control switches, wires, and the power source―from short-circuit and overcur-rent conditions. Specifying the right circuit protection device for an application is not difficult, but it does re-quire some thought. If electrical and electronic equipment is de-signed with over-specified circuit protection devices, the equipment will be vulnerable to the damaging effects of power surges and the catastrophic results of a fire, while using under-specified circuit protection devices will result in nuisance tripping.
