Frequently asked questions

What is the difference between a molded case switch and a circuit breaker?

A molded case switch, like the 3VA5210-1BB31-0AA0, is primarily designed for isolation and protection, often with intrinsic device protection. A circuit breaker typically offers more advanced trip unit options for specific overload and short-circuit settings.
