For the main contacts, the tightening torque range is 16 to 8 N·m, depending on the conductor size. The auxiliary contacts accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded. This part ships without an auxiliary switch block — you add one if the circuit needs a feedback or status contact. The 45 mm width leaves room for a three-pole overload relay or a second contactor in a reversing starter pair on the same rail. Keep the side clearance at 6 mm to adjacent devices for airflow and arc-flash containment — the arcing time is rated at 10 ms, so the gap is standard for this class. Depth is 141 mm, height 85 mm. When you're laying out the gland plate, account for the forward clearance of 10 mm and upward/downward clearance of 10 mm each for wiring and heat dissipation. The contactor can be mounted in any of the allowed positions listed above, so it adapts to vertical or horizontal panel orientations without derating.","metaTitle":"Siemens SIRIUS 3RT2024-1AL24-3MA0 Power Contactor, Size S0,","metaDescription":"Siemens SIRIUS 3RT2024-1AL24-3MA0 power contactor, Size S0, 45 mm width, screw and snap-on DIN rail mounting.
