It carries three 3-pole power poles (3 x 3P, all normally open), rated for 115 A in AC-3 duty, which means it handles the inductive load of a standard three-phase squirrel-cage motor up to that current. The coil is 220 V AC.
The AC-3 utilisation category tells you this starter is built for starting and stopping squirrel-cage motors under load — not for resistive heating or DC loads. The 115 A rating is the maximum motor full-load current it can switch in that duty. Fire resistance to 850 °C and V1 flame retardance on the housing mean it meets the thermal runaway containment expectations for panel-mounted switchgear.
Environmental and mechanical limits
Storage range is -60 to 80 °C. The protective treatment is TH conforming to IEC 60068-2-30, meaning it is tested for damp heat cyclic conditions — not tropicalised, but suitable for humid factory floors. Vibration resistance is 2 Gn (contactor open) and 4 Gn (closed) over 5-300 Hz; shock resistance is 6 Gn open, 15 Gn closed for 11 ms. These numbers matter if the starter is mounted on a machine that vibrates or sees impacts.
