2.1 Fuse protection against short-circuits
Fuse protection against short-circuits can be added to a three-phase supply
system in one of the following ways:
Table 4: Fuse protection EMS-…SWD for IEC applications
Table 5: Fuse protection EMS-… for UL applications
2.2 Derating rated operational current (EMS-…-SWD)
Depending on the installation situation and the maximum ambient air
temperature, it may be necessary to derate the maximum rated operational
current.
Derating is based on the following installation situations:
•
separate mounting,
•
connected in series with 30 mm clearance,
•
without clearance.
