Electrical: Busbar - Table 3: Quick Busbar Selector - Copper
WebWe recommend that you used the comb-type busbars listed on the corresponding pages in the current Wöhner catalogue ( IEC/EN 60439-1 or IEC/EN 61439-1/2, level of soiling: 2). Ensure that the required air and creepage distances left in standard installation positions are observed (comb-type busbars are angled towards the operator). Webrating is shown under the 42 kA column, and therefore is valid. Example 2: 480Y/277 volt, 3-phase, 4-wire, AC system with available fault current of 62,097 amperes. Main (upstream) device is a 3-pole 250 ampere, HJD breaker. The branch (downstream) breakers are 2- and 3-pole, 60, 70, and 100 ampere shell atf 3403 m-115
