Motor full-load current chart for 415 V three-phase induction motors from 0.37 kW to 160 kW (0.5 to 215 HP), with the matching contactor, overload relay and MPCB for each size.

Use it to size starters, cables and protection quickly. Values are typical for 4-pole IE2 motors at 415 V, 50 Hz. Always confirm with the current printed on your motor's nameplate. Prices checked 3 November 2026. Reviewed by Amit, Voltkart.

415 V motor full-load current chart (kW, HP and amps)

Rule of thumb: about 2 A per kW at 415 V. Contactor and relay pairings are for direct-on-line starting; for star-delta, set the overload relay to about 58% of the full-load current.

Full-load current by motor size: quick answers

What is the full-load current of a 5 HP (3.7 kW) motor?

A 5 HP (3.7 kW) three-phase motor draws about 7.5 A at full load on 415 V (typical 4-pole IE2 motor). For a direct-on-line starter use an LC1D09 contactor with an LRD14 overload relay, or a GV2ME14 MPCB. Check the motor nameplate for the exact current.

Motor current FAQs

How do I calculate the full-load current of a 3-phase motor?

Full-load current = kW × 1000 ÷ (√3 × voltage × power factor × efficiency). For a 7.5 kW motor at 415 V with a power factor of about 0.85 and efficiency of about 0.88: 7500 ÷ (1.732 × 415 × 0.85 × 0.88) ≈ 14 A, which is close to the 15 A in the chart. The motor nameplate always gives the exact figure.

Why is the current different on my motor nameplate?

Full-load current depends on the number of poles, efficiency class (IE1, IE2, IE3), power factor and the manufacturer. 2-pole and 6-pole motors and rewound motors can differ from the typical values here, so always set protection to the nameplate current.

What is the current of a 5 HP and a 10 HP motor at 415 V?

A 5 HP (3.7 kW) 3-phase motor draws about 7.5 A, and a 10 HP (7.5 kW) motor about 15 A at 415 V. A rough rule of thumb is about 2 A per kW at 415 V for small and medium motors.

How much current does a motor draw when starting?

A direct-on-line start draws about 6 to 7 times the full-load current for a few seconds. Star-delta starting reduces this to about one-third, and a VFD or soft starter limits it further.

What size contactor and overload relay do I need?

Choose a contactor whose AC-3 rating covers the motor kW, and an overload relay whose setting range includes the full-load current, then set it to the nameplate current. The chart above gives the usual Schneider pairing for 415 V DOL starters.
