The coil is 24 VDC with screw-type terminals, and the main contacts use screw terminals accepting 1 to 10 mm² solid or stranded wire. Mounting position allows +/-180° rotation on a vertical surface, plus forward/backward tilt of +/-22.5° on a vertical surface — useful when you're squeezing this into a crowded panel and need to angle the contactor for access. Clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side. The S0 frame is a standard Siemens size; if you're replacing an older S0 contactor from another SIRIUS generation, the footprint and DIN rail clip are identical. ## Operating conditions and switching performance Operating temperature range is -25 to +60 °C, storage from -55 to +80 °C. Maximum mechanical switching frequency is 1 000 1/h for AC-1, AC-2, AC-3, and AC-3e duty; AC-4 drops to 300 1/h. Arcing time is 10 ms. The contactor is rated for 10 000 000 typical mechanical operations — that's the mechanical life, not electrical, so derate based on your switching load. Coil operating times at AC are 4 to 16 ms. Auxiliary switch: none built in, so plan an external auxiliary contact block if you need status feedback.","metaTitle":"Siemens SIRIUS 3RT2024-1AN24 Power Contactor, S0 Frame, 24 V","metaDescription":"Siemens SIRIUS 3RT2024-1AN24 power contactor, S0 frame size, 24 VDC screw-type coil, screw and snap-on DIN rail mounting, active production.

The mechanical footprint, DIN rail clip, and terminal layout are identical — so yes, it drops into the same panel without rewiring the power circuit. The difference is strictly the coil voltage and type (AC vs DC). If your control circuit is 24 VDC, the 1AN24 is the correct choice; if you're on 230 VAC control, the 1AU60 fits."},{"question":"What is the depth of this contactor?","answer":"141 mm.
