S0 Frame Contactor for Motor Switching
The Siemens 3RT2326-1AB00 is a SIRIUS-branded contactor in the S0 frame size, designed for switching motor loads and resistive loads in control panels. It mounts on 35 mm DIN rail per DIN EN 60715 using either screw fixing or the snap-on latch, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward or backward. The coil is rated 24 VAC at 50 Hz with screw-type terminals, and the contactor carries one normally-open instantaneous auxiliary contact rated across a voltage range: 10 A at 24 V, 10 A at 230 V, 3 A at 400 V, and 1 A at 690 V. The auxiliary contact arcing time is 10 ms typical.
Panel Fit and Wiring Clearances
The contactor measures 97 mm deep, 60 mm wide, and 85 mm tall, fitting the standard S0 footprint. Required clearances around the unit are 10 mm upwards, 10 mm downwards, 10 mm forwards, and 6 mm at the sides — these matter when laying out multiple contactors side-by-side on the DIN rail to avoid thermal derating or arc flash between poles. Main circuit terminals accept stranded wire from 1 to 10 mm², while auxiliary and coil terminals accept solid wire 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). The screw-type terminals are standard for panel wiring with ring or fork lugs.
Environmental and Lifecycle Profile
Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C. The contactor is rated for 10 million mechanical operations typical, which suits high-cycle applications like conveyor systems or packaging machinery where the contactor cycles frequently. The lifecycle stage is listed as current production, meaning this order code remains an active catalog item from Siemens. No official successor or cross-reference is recorded — the 3RT2326-1AB00 is the part specified for new builds and replacement stock.
