The Siemens SIRIUS 3RT2015-1BB42-0CC0 is a size S00 power contactor with a 24 V DC magnet coil terminated at screw-type terminals. It carries an auxiliary switch and mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715 — the standard for panel builders who need a clean, tool-free rail fit alongside other S00 gear.
Switching capacity and duty-cycle limits
At the 24 V rated coil voltage, the main contacts switch 10 A. At 48 V and 60 V the rating drops to 2 A; at 110 V it is 1 A, at 125 V it is 0.9 A, and at 230 V it is 0.75 hp. The arcing time runs 10 to 15 ms, and the DC operating time is 7 to 13 ms.
Mechanical and thermal endurance
The contactor is rated for 30 million typical mechanical operations. Switching frequency depends on duty: 1000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor starting and running), 750/h at AC-3e, and 250/h at AC-4 (plugging and inching). Ambient operating range is -25 to +60 °C; storage range is -55 to +80 °C.
Mounting and clearances
Mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward. Minimum clearances to adjacent parts: 10 mm upwards and forwards, 10 mm downwards, 6 mm at the side. The footprint is 45 mm wide, 58 mm high, 73 mm deep.
Wiring and conductor sizes
Screw-type terminals accept solid or stranded conductors from 0.5 to 4 mm², and dual-wire combinations of 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².
