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. ## Lifecycle and sourcing — active production, quoted to order No stock-holding claim — quoted per order.","metaTitle":"Siemens 3RT2344-1AP00 SIRIUS Contactor, Size S3","metaDescription":"Siemens 3RT2344-1AP00 SIRIUS contactor, Size S3, screw and snap-on DIN rail mount.
