2) FLA – Full Load Current, maximum current for the entire mains voltage range as stated above (380 V – 500 V) according to UL/CSA
3) Only with "Fan" (standard equipment)
4) for group fuses: maximum fuse size: 30 A
5) Maximum mains short-circuit current, Note: Further restrictions are possible depending on the plug connector which is used (
