That means it drops into a standard panel footprint without adapter plates — the S3 frame carries the main power terminations and an integrated auxiliary switch block. Mounting position is flexible: the contactor can be rotated ±180° on a vertical surface and tilted forward or backward by ±22.5° on that same vertical surface, which helps when routing cables in a crowded enclosure. Main power conductors accept stranded wire from 6 to 70 mm², covering the range for motor circuits up to the S3 current class. Auxiliary and coil connections use screw-type terminals sized for 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded. Operating temperature range of -25 to +60 °C and storage range of -55 to +80 °C cover most industrial panel environments without derating concerns. ## Dimensions and clearances The contactor measures 152 mm deep, 96 mm wide, and 140 mm high. Minimum clearance to adjacent components: 10 mm upwards, 10 mm downwards, 20 mm forwards, and 10 mm at the side — useful numbers when laying out a DIN-rail section with multiple contactors side by side.","metaTitle":"Siemens 3RT2344-1AV00 SIRIUS Contactor, Size S3, 152 mm Dept","metaDescription":"Siemens SIRIUS contactor 3RT2344-1AV00, Size S3, screw and snap-on DIN rail mount, 152 mm depth, active production.
