    Is there a difference between a solid state contactor and a solid state breaker?

    A contactor makes a circuit; a breaker opens one. Google will give details.

    Does a solid state breaker use mechanical contacts that are swiched by the solid state component to trip when the voltage crosses zero, thereby reducing arc, or does all the load current flow through the solid state component?

    "Solid state" implies no moving parts. Look up "ssr".

    If the above is true and there are no moving parts, what would be the difference between a form "B" contactor (normally closed) and a solid state breaker?

    Is it simply that the solid state breaker has to be reset when tripped while a form "C" solid state contactor will reset as soon as power is interrupted?


    I have been looking at google but am still wondering. Thanks!
