Rated 185 A in AC-3 duty (switching squirrel-cage motors) at up to 440 V, it handles motor loads up to 160 kW at 380/400 V and 185 kW at 440 V. The control circuit is 230 V AC 50/60 Hz, with an inrush draw of 805 VA at 50 Hz and 970 VA at 60 Hz.
The 185 A AC-3 rating is the key selection number — it tells you the continuous current the starter can handle while switching motor loads under full load. AC-3 covers starting and plugging of cage motors, which is the standard duty for a star-delta starter. The motor power table gives you the matching kW at common line voltages: 160 kW at 400 V, 185 kW at 440 V, and 90 kW at 230 V. Match your motor's nameplate to these figures — the starter is sized for the motor, not the other way around. The pre-wired assembly includes three contactors with specific auxiliary contact configurations: 1 NC + 1 NO on the star contactor, 2 NC + 1 NO on the line contactor, and 1 NC + 2 NO on the delta contactor. This is the standard complement for a star-delta sequence and saves you wiring time. Rated insulation voltage is 1000 V per IEC 60947-4-1.
This is a plate-mount assembly, not a DIN-rail snap-on. The footprint is 525 mm wide by 235 mm deep by 110 mm tall, so plan your enclosure backplate space accordingly. Power connections use M8 bolts with lugs or busbars up to 150 mm²; control wiring is screw-clamp terminals. Rated for operation up to 3000 m altitude without derating, so it works at most plant elevations without a second thought.
Compliant with IEC 60947-4-1, EN 60947-4-1, and JIS C8201-4-1.
