Overview
The term "series connected short circuit rating" refers to the application of series circuit breakers in a combination that allows downstream breakers to have lower individual interrupting ratings than the available fault current. This is permitted as long as the series combination has been tested and certified by CSA. The tables on these pages list specific main and branch breaker combinations that may be used for the short circuit interrupting ratings shown. No substitutions are permitted. All combinations shown have been tested and are CSA certified. This information is provided as a reference tool only. The interrupting rating of a circuit breaker is 5,000 RMS symmetrical amperes and for A fused switch 10,000 RMS symmetrical amperes, or as marked on the device, except for the series combination ratings shown on the following pages. Note: A load side circuit breaker may be a branch, submain, an integral main, or a remote main. The series combination interrupting rating shall not exceed that of the line side circuit breaker or fused switch or the marked short circuit rating indicated on the equipment. Quality and satisfaction is guaranteed.
