Rated for AC-3 duty up to 690 V, this contactor handles 10.5 kW at 400 V and 18 kW at 690 V (both at 60 °C ambient), making it a fit for 3-phase induction motors on pumps, conveyors, and compressors within that power band. The AC-3 rating governs the switching of squirrel-cage motors during starting and plugging — the most common load type in industrial automation. Mechanical life is rated at 30,000,000 operating cycles typical, with AC-3 electrical endurance at 750 cycles per hour maximum. That duty cycle suits applications with frequent starts but not continuous jogging — for high-inertia loads or repetitive inching, the AC-4 rating of 250 cycles per hour is the governing limit. ## Mounting and integration — DIN rail, screw terminals, side-by-side Main circuit and auxiliary/control connections use screw-type terminals. The main terminals accept 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or 2x 4 mm² solid or stranded copper — sized for the 10.5 kW motor circuit at 400 V. The product extension for auxiliary switches is available, so you can add a mirror contact or early-make/early-break block without replacing the base contactor. This is useful for feedback to a PLC or for interlocking in reversing starters. ## Lifecycle and sourcing — active production, quoted to order The paperwork has to be clean: the 48 V DC coil and SIRIUS brand are well-documented for customs clearance.","metaTitle":"Siemens 3RT6015-1BW41 SIRIUS Power Contactor, 48 V DC Coil","metaDescription":"Siemens SIRIUS 3RT6015-1BW41 power contactor, size S00, 48 V DC coil, 690 V AC-3 max, screw terminals, DIN rail mount.
