The Siemens SIRIUS 3RT2036-1NF34 is a size S2 power contactor rated for a coil voltage range of 83-155 V AC/DC, with screw-type terminals on the magnet coil. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, fitting a standard panel enclosure with a 55 mm width and 174 mm depth. The contactor is rated for AC-1 resistive loads up to 1,000 switching cycles per hour, AC-3 motor loads up to 800 cycles per hour, and AC-4 plugging/reversing duty up to 250 cycles per hour — the AC-3 figure governs most conveyor and pump applications.
The mounting position allows +/-180° rotation on a vertical surface and can be tilted forward/backward by +/-22.5°. Clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side — plan for these gaps in the panel layout to avoid thermal derating or arc flash interference.
