Product Overview and Key Ratings
The Siemens SIRIUS 3RT2036-3XJ40-0LA2 is a size S2 contactor designed for switching motor loads and resistive loads in industrial control panels. It is rated for a continuous current of 52 A at both 480 V and 600 V, making it suitable for 3-phase motor circuits up to that current level. The coil is DC-operated with a rated value of 72 V, and the contactor features an extended operating range for reliable pick-up under varying control voltage conditions.
Mounting and Integration
This contactor mounts via screw or snap-on onto a 35 mm standard mounting rail per DIN EN 60715. The mounting position allows +/-180° rotation on a vertical surface and can be tilted forward/backward by +/-22.5°. For panel layout planning, the dimensions are 55 mm width, 114 mm height, and 130 mm depth. Required clearances: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side. The main contacts accept solid or stranded wire: 2x (0.5... 2.5 mm²).
Switching Capacity and Duty Ratings
The contactor's switching capacity is specified per voltage for DC-1 or similar resistive/inductive loads. At 24 V it switches 6 A; at 48 V and 60 V, 2 A; at 110 V, 1 A; at 125 V, 0.9 A; at 220 V, 0.3 A; at 400 V, 3 A; at 500 V, 2 A; at 690 V, 1 A. For motor duty at 230 V, it is rated 10 hp. The AC-4 maximum switching rate is 250 operations per hour. Mechanical endurance is typical 10,000,000 operations. Arcing time is 10... 20 ms.
