Approximate Values for three-phase Motors
Motor Full Load Currents
Approximate values of motor F.L.C. and minimum „slow blow“ respectively „gL“ short-circuit fuse
The motor F.L.C. be valid for standard internal and surface cooled three-pole
motors with 1500 min
-1
. The fuses values be valid for the motor F.L.C. shown in
the table and D.O.L.-start: starting current max. 6x motor F.L.C., starting time
max. 5s; star-delta-start: starting current max. 2x motor F.L.C., starting time
max. 15s. For motors with higher F.L.C., higher starting current and / or longer
starting time, larger short-circuit fuses are required.
The maximum admissible value is dependent on the switchgear
respectively thermal overload relay.
