-
The fuse used in this UL test is an envelope (umbrella) fuse. This fuse is designed as a “worst case’’ fuse. Thus, no matter what manufacturer’s fuse is used, the
Square Dbrand circuit breaker is protected. -
The line side fused switch may be in a separate enclosure or in the same enclosure as the loadside breaker. A line side fused switch may be a submain, integral main, or remote main. A load side breaker may be a branch, submain, or an integral main used on the load side of a remote main. This series combination short circuit current rating shall not exceed that of the line side fused switch. The charts apply to Square D brand load side breakers only. However, the line side fuse ratings are independent of the fuse manufacturer.
-
Not applicable to Corner Grounded Systems.
-
Limiters used in Square D brand DSL and DSL II fused power circuit breakers are not class L fuses and do not have series ratings.
