What It Is & Key Ratings
The 3RT2015-2AN22: This is a Siemens SIRIUS power contactor in the compact S00 frame size. It's rated 10 A at 24 V and 3 A at 400 V — those are the AC-1 resistive load figures, so they govern the continuous current the main contacts can carry in a resistive circuit. For motor duty (AC-3), the switching frequency maxes out at 750 operations per hour, which is typical for a contactor this size in a conveyor or pump start application. Coil connection uses spring-type terminals. Main contacts configured as 20... 12. Auxiliary switch included.
Mounting & Integration
Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The mounting position is flexible: +/-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. Dimensions: 45 mm wide, 70 mm high, 73 mm deep — fits standard S00 contactor footprint. Wire range: accepts 0.5... 4 mm² solid or stranded (2x 0.5... 4 mm² for paralleled conductors). Operating temperature -25 to +60 °C; storage -55 to +80 °C. Mechanical service life is 30 million operations typical — that's the coil and mechanism, not the contacts under load.
