Spring-loaded terminals on both the main and auxiliary/control circuits accept 2x (0.25...2.5 mm²) solid or stranded, or 2x (24...14 AWG). The front face carries IP20, so panel builders can route wiring without finger-safety covers at the operator interface. ## Coil and switching duty Coil is 24 VDC rated, pickup at 0.85x nominal (20.4 V), dropout at 1.1x (26.4 V). Closing and holding power both 3.3 W — the magnet circuit is a DC economized design, so the coil draw does not spike on seal-in. For motor switching: AC-2 duty (slip-ring motors, wound-rotor lifts) is 3 kW at 400 V; AC-4 duty (plugging, inching) is 6.5 A at 400 V. The AC-12 maximum operational current is 10 A for resistive loads on the auxiliary side. ## Coordination and environment","metaTitle":"3RT1015-2BB41 SIRIUS Power Contactor, S00, 24 VDC, 3 kW AC-2","metaDescription":"Siemens SIRIUS 3RT1015-2BB41 power contactor, size S00, 24 VDC coil, 3 kW at 400 V AC-2, spring-loaded terminals, DIN-rail mount.
