It is rated for AC-3 utilisation category, delivering 100 kW at 220/230 V AC, 200 kW at 380/400 V and 415 V, and 220 kW at 440 V — all at 50/60 Hz. This covers the common European and North American motor voltage bands from a single order code. The starter integrates three contactors (line, delta, star) with a 3 x 3 NO power pole composition and a specific auxiliary contact arrangement: 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 pre-configured set saves panel wiring time and reduces the chance of mis-wiring the interlock sequence.
The AC-3 rating is the motor-switching duty cycle — making and breaking locked-rotor currents. The 100–220 kW range across voltages means this starter handles a 225 A motor full-load current class. The rated making capacity is 2250 A and the breaking capacity is 1800 A per IEC 60947-4-1, which confirms it can close onto and interrupt starting surges without contact welding. The closing time is 20–35 ms and opening time 7–15 ms, which is fast enough for standard motor protection coordination. Heat dissipation runs 18–24 W, so panel thermal rise is manageable even in a densely packed enclosure. The control circuit is AC 50/60 Hz at 220/230 V, with an inrush of 805 VA at 50 Hz and 970 VA at 60 Hz. The pickup/drop-out limits are 0.85–1.1 Uc for operation and 0.35–0.55 Uc for drop-out, which gives a reliable hold-in margin on a typical control transformer. The associated fuse rating is 315 A gG or 250 A aM up to 440 V, which sets the short-circuit protection boundary for coordination studies. The rated insulation voltage is 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 group C, so it is suitable for 690 V systems with proper isolation.
This is a plate-mount assembly, not DIN-rail — the footprint is 525 mm wide, 235 mm deep, and 110 mm tall. Power connections use M10 bolted lugs or busbars accepting up to 185 mm² cable or a 32 x 4 mm busbar. Control wiring is via screw clamp terminals accepting 1–4 mm² flexible or solid wire. The IP20 front face with shrouds per IEC 60529 and VDE 0106 is standard for enclosed panel mounting. The starter is pre-wired internally, so the panel builder only needs to bring in the main power, motor leads, and control voltage. The tightening torque for power connections is 35 N·m and for control circuits 1.2 N·m.
Standards compliance includes IEC 60947-1, IEC 60947-4-1, EN 60947-1, EN 60947-4-1, and JIS C8201-4-1. This covers the essential motor starter standards for most global projects.
