It snaps onto a 35 mm DIN rail per DIN EN 60715, and its mounting position is flexible — it can be rotated ±180° on a vertical surface and tilted ±22.5° forward or backward.
The 3RT2015-1AN22 is rated for 10 A at 24 V, 2 A at 48 V, and 3 A at 400 V for its auxiliary contacts — these are the switching limits for control circuits at those voltages. For the main contacts, the mechanical service life is typical 30 million operations, and the maximum operating frequency varies by duty: 1,000 cycles/hour for AC-1 (resistive loads), 750 cycles/hour for AC-3 (squirrel-cage motor starting), and 250 cycles/hour for AC-4 (plugging/inching). The contactor measures 45 mm wide, 58 mm high, and 73 mm deep, with clearance requirements of 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the side.
