The Siemens 3RT2015-1BB41-ZW97 is a SIRIUS power contactor in Size S00, with a 24 VDC magnet coil and screw-type terminals. It mounts on a 35 mm DIN rail per DIN EN 60715, using either screw or snap-on fastening, and fits a 45 mm wide slot in the panel. The auxiliary switch is built in. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C.
Key Ratings and Fit
The coil pulls 10 A at 24 V rated value, with a holding dropout below 0.8 of initial value. Main contact ratings cover AC-1 through AC-4 duty cycles: up to 1 000 operations/hour at AC-1, 750/h at AC-2 and AC-3, and 250/h at AC-4. The contactor is rated for switching motor loads in control panels — the AC-3 duty cycle is the one that governs real motor-starting applications. Dimensions are 73 mm depth, 45 mm width, 58 mm height. Wire range accepts solid or stranded 0.5 to 4 mm², with multiple conductor combinations supported. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, giving flexibility in tight enclosures.
