Fuse calculations
Fuse calculations for IEC are done according to 60364-4-43 electrical installations of buildings,
part 4: protection for safety- section 43: protection against overcurrent. Fuse sizes are calculated
in order to protect the cable against short circuit. Fuse type aM is recommended but gG/gL is
also allowed.
For UL designed machines, calculations of fuses are done according to UL508A (Industrial
control panels).
For CSA, calculations of fuses are done according to CSA 22.2 (Canadian electrical code).
Fuse size is the maximum fuse size in order to protect the motor against short circuit.
• For CSA: fuse HRC form II
• For UL: fuse class J or RK5
If the local conditions are more severe then the described standard conditions, the fuses for worst
case conditions should be used.
