The 115 A rated operational current (at ≤ 440 V AC, AC-3, <131 °F) corresponds to motor power ratings of 52 kW at 220/230 V, 85 kW at 380/400 V, and 102 kW at 415/440 V, all at 50/60 Hz.
The 115 A AC-3 rating is the headline selection parameter — it governs the motor current the starter can handle during starting and running. The associated fuse ratings (200 A gG or 125 A aM up to 440 V) give the upstream protection window. The rated making capacity of 1150 A and breaking capacity of 920 A (per IEC 60947-4-1) confirm it can close onto and interrupt locked-rotor currents without welding or arcing damage. The control circuit is AC 50/60 Hz at 220/230 V, with an operational voltage range of 0.85...1.1 Uc and a drop-out range of 0.35...0.55 Uc at 55 °C — so the coil holds in reliably down to about 187 V and drops out below about 127 V. Operating time is 23...35 ms closing and 5...15 ms opening, with a maximum operating rate of 2400 cycles per hour at 55 °C. Mechanical durability is 10 million cycles, and the unit is rated for vibrations of 2 Gn (open) and 6 Gn (closed) across 5...300 Hz, plus shock resistance of 9 Gn (open) and 15 Gn (closed) for 11 ms — figures that matter for installations on mobile equipment or near heavy machinery.
This is a plate-mounted unit, not DIN-rail snap-on — plan for bolted installation using the M6 power-circuit connections. Power wiring accepts bar (20 x 3 mm busbar cross-section), bolted lugs, or ring terminals up to 95 mm². Control wiring uses screw-clamp terminals accepting 1...4 mm² flexible with cable end, or 1...4 mm² solid without. The front face achieves IP20 with shrouds (per IEC 60529 and VDE 0106), so it is suitable for enclosed panels where operators do not contact live parts.
The starter complies with EN 60947-1, IEC 60947-4-1, EN 60947-4-1, IEC 60947-1, and JIS C8201-4-1. Rated insulation voltage is 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 Group C. The protective treatment is TH (tropicalised humidity resistance), and storage temperature range is -60...80 °C.
