That rate suits conveyor and pump cycling in automated lines where the contactor sees frequent on-off commands across a shift. When laying out a row of contactors, the side clearance is the tightest constraint — 6 mm between units keeps the arc chamber venting unobstructed. Auxiliary contact wiring (if fitted) takes 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded. The screw-type coil terminals match the main contact termination style, keeping the wiring kit consistent across the panel. The product carries the SIRIUS brand under Siemens catalog, with no official successor order code listed. For a panel originally specified around a different S0-frame contactor such as 3RT2024-1AU60, verify coil voltage and auxiliary contact configuration before drop-in substitution — the mechanical footprint and DIN rail mounting are identical, but the coil circuit and aux contact count may differ.","metaTitle":"Siemens 3RT2024-1AB04 SIRIUS Power Contactor, Size S0, 45mm","metaDescription":"Siemens 3RT2024-1AB04 SIRIUS power contactor, Size S0, 45mm width, screw terminals.
