Tab. 11-4: Line cross sections and fuses according to UL508A:2007, Table 28.1
Dimensioning variables of the table values
1. Ambient temperature T
A
of routed lines ≤ 40 °C
2. Temperature T
L
at conductor at nominal current: 90 °C for UL-listed
lines (USA/Canada) or 70 °C for PVC lines
3. The nominal current of the fuse is approx. 10-20% above the nominal
current I
LN
of the converter/supply unit or the determined current of the
drive system.
4. Installation types:
● B1 in accordance with IEC 60364-5-52, e.g. stranded wires routed
in cable duct
● B2 in accordance with IEC 60364-5-52, e.g. multi-core line routed
in cable duct
● E in accordance with EN 60204-1, e.g. multi-core line routed on
open cable tray
● In accordance with NFPA 79 (external wiring), UL508A (internal
wiring), NEC, NFPA 70:
– 1 cable with 3 conductors, 1 neutral conductor and 1 equip‐
ment grounding conductor
– Routed in pipe on the wall
Internal wiring: Routing inside of control cabinet or inside of devi‐
ces
External wiring: Routing outside of control cabinet
Field wiring: Data of cross sections of terminal connectors wired by
the user (in the field)
5. Recommendation for design of the fuses:
● International except for USA/Canada:
– Fuse-link in accordance with IEC 60269-1, characteristic gG
(fuses)
– Circuit breakers in accordance with IEC 60898-1/2, type B or
C
– Circuit breakers in accordance with IEC 60947-2/6-2
