■ Rated currents of 3-phase motors (approx. figures for squirrel-cage motors)
Minimum fuse size for protection of 3-phase motors
The maximum size is determined by the requirements of the switchgear or overload relay.
The rated motor currents are for standard 1500 r.p.m. 3-phase enclosed ventilated and totally enclosed fan-cooled motors.
D.O.L. starting:
Y/D starting:
Rated fuse currents for Y/D starting are also valid for 3-phase motors with slip-ring motors.
For higher rated currents, starting currents and/or longer starting times, larger fuses are required.
Table is valid for “slow” and/or “gL” fuses (DIN VDE 0636).
For NH fuses with aM characteristics, fuses = rated current is selected.
