Circuit Breakers
Circuit Breakers
(OP)
It is found that circuit breaker shall satisfy that the r.m.s symetrical breaking current for which the device is rated is to be not less than the r.m.s value of the a.c component of the prospective fault current, at the first half cycle.(previously at the instant of contact separation).
*Revision*
"Instant of contact separation --> the first half cycle"
It looks that circuit breaker should be selected as more breaking capacity in selecting Circuit breaker as per the above revision. IS that right ? What does that mean ?

RE: Circuit Breakers
"Instant of contact separation" sounds as if it would apply to a special class of equipment known as "current limiting".
What code are you referring to?
