The 3RT2344-1AP00: Main contacts are rated 10 to 2 A — the lower figure likely reflects the AC-3 motor switching duty cycle where contact wear accelerates; the 10 A figure is the thermal continuous rating at lower switching frequencies. Arcing time is 10 to 21 ms at AC, which means the contactor clears the arc within one to two half-cycles at 50/60 Hz — important for coordinating upstream fuse or breaker trip curves. Mechanical endurance is 10 million operations typical — this is the contactor body life before spring fatigue or wear-out, not the electrical life under load (which is lower at rated current).
Wire terminations — power and auxiliary circuits
Power circuit accepts stranded wire from 6 to 70 mm² — covers most motor feeds up to about 50 HP at 400 V depending on duty cycle. The magnet coil uses screw-type terminals, rated 230 V at 50 Hz, with a power factor of 0.38 — the low PF means the coil draws higher VA than the wattage suggests, so size the control transformer for inrush.
