  • Hi OMS,


    Isn't all this parameters elated to the circuit breaker?


    When someone says, what is the short circuit rating of the switchgear assembly (the whole structure), what does it usually refers to?

    Is it the busbar rating?

    Is it the Main Incomer circuit breaker breaking capacity?

    Is it the whole assembly withstand capacity?
