The screw-type terminals on both main and auxiliary circuits accept 2x (0.5 to 1.5 mm²) solid/stranded, 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²) — or 1x 12 AWG. That covers typical panel wiring without needing ferrules, though ferruled stranded is fine. The S00 frame is compact at 45 mm wide, 57.5 mm tall, and 111 mm deep — fits a standard 45 mm slot in a control panel, and side-by-side mounting is allowed without derating for the thermal current. Pollution degree 3 (conductive or dry non-conductive pollution) is standard for industrial control panels. The contactor is rated for type 1 coordination with a 35 A gL/gG fuse, and type 2 coordination with a 20 A gL/gG fuse — that's the short-circuit protection you need upstream to keep the contactor serviceable after a fault. For compliance documentation, the manufacturer provides RoHS and REACH declarations; UL and IEC certifications are standard for the SIRIUS line but not individually listed in this spec set.","metaTitle":"Siemens 3RT1017-1BB44-3MA0 SIRIUS S00 Power Contactor, 24 V","metaDescription":"Siemens SIRIUS S00 power contactor 3RT1017-1BB44-3MA0, 24 V DC coil, 10 A rated operational current, IP20, screw terminals, DIN rail mount.
