Read: Contactor Sizing for 400 V and 415 V Motors: kW to Amps, AC-3 Ratings and Overload Relays →
What size contactor do I need for a 7.5 kW motor?
A 7.5 kW three-phase motor at 400 V draws about 14.5 A, so a contactor rated at least 16 to 18 A at AC-3 is the usual choice, with an overload relay set to the nameplate current.
What is the difference between AC-1 and AC-3?
AC-1 is the rating for resistive loads such as heaters; AC-3 is the rating for switching squirrel-cage motors in normal duty. Motors are always sized on the AC-3 figure, which is lower.
How many amps per kW for a three-phase motor?
At 400 V, roughly 2 A per kW for small motors, falling towards about 1.8 A per kW above 30 kW, because larger motors run at a better power factor and efficiency. Use the nameplate for the exact figure.
