Hey folks,
Why is it that when I look in AB catalog unfer combination starters (513, 1233x) the Max. Available Amperes for the starters is based on type of enclosure?
I need starters for a system with approximately 20kA available @ 600V. From the literature this means if I buy a NEMA 4x box a size 4 would could handle 10kA but then if I buy a NEMA 1, 4 or 12 it is good for 25kA...
Regards,
TULUM
