The Siemens 3RT2046-3XJ44-0LA2 is a SIRIUS contactor in size S3, designed with an extended operating range and a DC coil rated at 72 V. It uses spring-type terminals for the magnet coil, and the main contacts are rated for switching at 480 V up to 96 A. The contactor mounts via screw or snap-on onto a 35 mm DIN rail per DIN EN 60715, with a width of 70 mm and a depth of 200 mm — dimensions that fit standard panel layouts.
The mounting position allows ±180° rotation on a vertical surface, plus ±22.5° tilt forward/backward on a vertical surface. Clearances: 10 mm upwards, 20 mm forwards, 10 mm downwards, 10 mm at the side. The 70 mm width and 200 mm depth fit standard DIN-rail enclosures without crowding adjacent devices.
