Substance prohibitance compliance is documented with a date of 03/01/2017, confirming the part meets RoHS and REACH substance restrictions effective from that date. Size S3 form factor with screw terminals accepts 2x (2.5... 16 mm²) solid or stranded conductors on the main circuit, and 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²) finely stranded with core-end processing on the auxiliary side. Fastens via screw and snap-on mounting onto 35 mm and 75 mm standard DIN rails; mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, giving flexibility in dense panel layouts.","metaTitle":"Siemens 3RT5046-1AK20 SIRIUS Power Contactor, AC-3 45 kW 400","metaDescription":"Siemens SIRIUS 3RT5046-1AK20 power contactor, 120 V 50/60 Hz coil, AC-3 45 kW at 400 V, 3-pole size S3, screw terminals.
