Minimum fuse size for shortcircuit protection of 3phase motors. The maximum size is determined by the requirements of the switchgear or overload relay The rated motor currents are for standard 10 r.p.m. 3phase enclosed ventilated and totally enclosed fancooled motors. D.O.L. starting : maximum starting current x rated motor current. Maximum starting time : 5 s. Y/Δ starting : maximum starting current x rated motor current. Maximum starting time : 15 s. set overload relay in the phase lead to 0.58 x rated motor current. Rated fuse currents for Y/Δ starting are also valid for 3phase motors with slipring rotors. For higher rated currents, starting currents / longer starting times, larger fuses will be required. Table is valid for 'slow' / 'gl' fuses (DIN VDE 03) For NH fuses with am characteristic, fuses = rated current selected.
