The Siemens SIRIUS 3RT2015-2AP02-ZW97 is a Size S00 power contactor built for switching motor loads in control panels. It carries a 24 VDC coil and spring-type terminals — the kind that save you a turn of the screwdriver on a crowded DIN rail. Rated for 30 000 000 typical mechanical operations, so it outlasts most of the gear it switches.
DIN-rail fit and panel clearances
Mounts via screw or snap-on onto 35 mm standard mounting rail per DIN EN 60715. The 45 mm width and 73 mm depth fit a standard 8-module DIN pitch. Keep 10 mm clearance upwards, forwards, and downwards, and 6 mm at the side for heat rise and arc chutes.
Wiring and terminal specs
Spring-type terminals accept solid or stranded wire from 0.5 to 4 mm², and you can double-terminate two wires of the same range in one clamp. Main contacts handle 20 to 12 AWG. The coil connection is also spring-clamp, so no screw torque to verify.
Switching performance and duty cycles
Rated for 1 000 operations per hour at AC-1 resistive load, 750 ops/h at AC-2 and AC-3 motor duty, and 250 ops/h at AC-4 plugging/reversing. Pickup time is 7 to 13 ms at AC; arcing time runs 10 to 15 ms. That 0.25 A coil draw at 50/60 Hz means the control transformer doesn't break a sweat.
Thermal limits and environment
Operates from -25 to +60 °C, stores from -55 to +80 °C. The mounting position is flexible — you can rotate it ±180° on a vertical surface or tilt it ±22.5° forward or backward. That helps when you're squeezing it into a tight gland plate layout.
