What It Is and Where It Fits
The Siemens SIRIUS 3RT2024-1AP00-ZW96 is a power contactor in the S0 frame size, designed for switching motor loads and resistive loads in industrial control panels. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, making it a direct fit for standard panel layouts. The 24 VDC coil with screw-type terminals is the primary control interface, and the contactor includes an integrated auxiliary switch block for feedback or interlocking circuits. Rated for continuous operation from -25 to +60 °C, with storage tolerance from -55 to +80 °C, it handles the thermal range of most enclosed panels without forced cooling.
What the Ratings Mean for Your Panel
The auxiliary contact ratings tell you what control voltage you can switch: 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 230 V, and 3 A at 400 V. At 480 V it handles 11 A — that covers most North American control transformer secondaries. Mechanical endurance is rated at 10,000,000 operating cycles typical, with switching frequency limits of 1,000 1/h for AC-1, AC-2, AC-3, and AC-3e duty, and 300 1/h for AC-4 — the heavier the switching arc, the slower you must cycle. Wire range accepts 1 to 10 mm² solid or stranded on the main power circuit, with finer 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) for auxiliary wiring. The screw terminals are the standard captive-clamp type.
Mounting and Clearance
The S0 frame measures 85 mm high, 45 mm wide, and 97 mm deep — a compact footprint that fits alongside other S0 devices on the same DIN rail without crowding. Mounting position is flexible: the contactor can be rotated ±180° on a vertical surface and tilted forward/backward ±22.5°, which helps when fitting into tight enclosures or legacy layouts. Clearance requirements are specified: 10 mm upwards, 10 mm downwards, 10 mm forwards, and 6 mm at the side — plan your DIN rail spacing and enclosure depth accordingly to avoid arc flash or heat buildup.
Lifecycle and Sourcing Reality
For buyers with an existing BOM line specifying the 3RT2024-1AP00-ZW96, the active lifecycle means no immediate replacement engineering is needed. The part is available for quotation on a per-order basis.
