2 Overview Introducing the EG AC Series of Molded Case Circuit Breakers now available with UL489 certification. Available in four different compact frames, the New AC Series will assure top performance for both thermal and short-circuit protection from 15 to 800Amps. The AC series is also available in two levels of short-circuit interrupting capacity for standard industrial and commercial standard applications and for high-performance applications. Common plug-in accessories simplify field installation and minimize inventory variations on distributors shelves.

17 Cascading protection This is an economical approach to the use of circuit protective devices, whereby only the main (upstream) breaker has adequate interrupting capacity for the maximum available fault current. Downstream circuit breakers cannot handle this maximum fault current and rely on the opening of the upstream breaker for protection. The advantage of this approach is that it facilitates the use of downstream low cost, low fault level breakers, thereby offering savings in both the cost and size of equipment. These ratings, however, are applicable only when the seriesconnected devices have been investigated by UL in combination with the end-use equipment and the equipment in which these devices are used is marked with the series-connected rating. ower supply 240V Main breaker AC125 AC125 AC250 AC250 Branch breaker Rated breaking capacity (karms) AC AC AC AC AC AC AC AC Main breaker AC400 AC400 AC800 AC800 Branch breaker Rated breaking capacity (karms) AC AC AC AC AC AC AC AC ower supply 480V Main breaker AC125 AC125 AC250 AC250 Branch breaker Rated breaking capacity (karms) AC AC AC AC AC AC AC AC Main breaker AC400 AC400 AC800 AC800 Branch breaker Rated breaking capacity (karms) AC AC AC AC AC AC AC AC Data is subject to change without notice ASK-4EG 17

19 Selectivity (Coordination tables) Definition of selectivity is given by the IEC "Trip selectivity is the coordination between the operating characteristics of two or more overcurrent protection devices, so that when an overcurrent within established limits occurs, the device intended to operate within those limits trips whereas the others do not trip". The definitions of total selectivity and partial selectivity are, on the other hand, given in art 2 of the same Standard IEC "Low voltage Equipment - art 2: Circuit-breakers" "Total selectivity" Overcurrent selectivity where, in the presence of two protection devices against overcurrent in series, the load-side protection device carries out the protection without making the other device trip." "artial selectivity" Overcurrent selectivity where, in the presence of two protection devices against overcurrent in series, the load-side protection device carries out the protection up to a given level of overcurrent, without making the other device trip." Selection of proper protection system is fundamental to guarantee correct economical and functional service of the whole installation and to reduce the problems caused by abnormal service conditions or actual faults to a minimum.

Example The following two circuit-breakers are considered: - Main breaker AC (Icu = 65kA) - Branch breaker AC (Icu = 65kA) Extracting the data from the table above, it can be seen that there is total selectivity (T) between these circuit-breakers. In other words, there is selectivity up to 65kA (the lower of the two values). Now the following two circuit-breakers are considered: - Main breaker AC (Icu = 65kA) - Branch breaker AC (Icu = 65kA) Extracting the data from the table above, it can be seen that the selectivity value is 50kA between the two circuit-breakers. This means that, if the maximum prospective short-circuit current on the load-side of the AC circuit-breaker is less than 50kA, there will be total selectivity, whereas if the short-circuit current has a higher value, there will be partial selectivity (non-tripping of the supply-side circuit-breaker is not guaranteed).

27 Characteristics curves - Current limiting The following curves show circuit breaker current-limiting characteristics. The rms of the prospective symmetrical short-circuit current is indicated on the abscissa of the diagram, whereas the peak short-circuit current value is indicated on the ordinates. The current-limiting effect can be visualized by comparing, at the same symmetrical short-circuit current value, the corresponding peak value at the prospective short-circuit current with the limited peak value. In correspondence to a short-circuit of 40kA@480V, the AC125 circuit breaker would limit the peak value to approximately 16kA@480V.
