SIRIUS S2 Contactor, AC Coil — Panel Fit and Ratings
The Siemens 3RT2336-1AU00 is a size S2 SIRIUS contactor with an AC coil, screw-type terminals, and a rated mechanical life of 10,000,000 operating cycles. It occupies 75 mm width, 114 mm height, and 130 mm depth on the DIN rail, with side-by-side mounting permitted at 6 mm spacing to adjacent units. The coil operates on AC voltage; the main contact rating spans 18 A down to 1 A depending on the utilization category. For a panel-builder, the 75 mm width and 130 mm depth mean this contactor fits standard S2 cutouts and leaves room for auxiliary contact blocks — up to two attachable blocks. The screw-type coil terminals accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²) for the main circuit wiring. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, which helps when routing cables in a crowded enclosure.
Integration and Environmental Limits
Fastening is by screw and snap-on onto 35 mm DIN rail per DIN EN 60715. Ambient operating temperature range is -40 to +70 °C; storage range is -55 to +80 °C. The contactor includes one instantaneous auxiliary contact and accepts an auxiliary switch module. Clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side.
