The Siemens 3RT2015-2AK61-ZW97 is a SIRIUS power contactor in the compact Size S00 frame — 45 mm wide, 70 mm tall, 73 mm deep — built for switching motor loads and resistive circuits in control panels. Mounting is via screw or snap-on onto 35 mm DIN rail per EN 60715, and the contactor can be rotated ±180° on a vertical surface or tilted ±22.5° forward/backward, giving panel builders flexibility in tight enclosures.
Switching Duty and Auxiliary Contact Ratings
Maximum switching frequency varies by duty class: 1 000 operations per hour under AC-1 (resistive loads), 750/h under AC-2 and AC-3 (slip-ring and squirrel-cage motors), and 250/h under AC-4 (plugging/inching) (–,). The auxiliary switch is rated at 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V (–); these are the values that govern whether the auxiliary contacts can handle the pilot-duty load in your specific control circuit — a 24 VDC PLC output sinking 0.5 A is fine, but a 220 VAC valve solenoid drawing 0.4 A is at the edge of the 0.3 A rating and needs a separate interposing relay.
