SIRIUS S00 contactor, 12 A, 5.5 kW AC-3
The Siemens 3RT2317-2AP00 is a SIRIUS size S00 contactor rated for 12 A at 400 V, with an AC-3 motor switching capacity of 5.5 kW at 400 V — that's the rating that governs real motor loads like pumps and conveyors, not the resistive AC-1 figure. The coil is AC-operated at 230 V, 50/60 Hz, drawing 0.25 A. Spring-loaded terminals on both the main and auxiliary circuits accept 0.5 to 4 mm² stranded or 2x 0.5 to 2.5 mm² solid, so no lug crimping needed for panel wiring up to that gauge.
For a panel originally wired around the 3RT2015-2AP01, the 3RT2317-2AP00 shares the same S00 frame size and DIN rail footprint, so it drops in without rewiring — but verify the coil voltage and auxiliary contact configuration against your BOM.
