Table 2-2 Braking circuit cable and fuse ratings for NBRA-658, NBRA-659 and NBRA-669.
1)
Ultrarapid Bussmann fuses (U
N
= 1250 V). Fuses with the same ratings from other manufacturers can also be used.
The type of the base for these fuses is 170H3005 (1400 V, 630 A, 110 mm).
2) In order for the installation to comply with the EMC Directive, unscreened single-core cable can only be used if routed inside a
cabinet that efficiently suppresses the radiated RFI emissions.
