SIRIUS Power Contactor, Size S00 — 24 VDC Coil, Screw Terminals
The Siemens 3RT2015-1CP04-3MA0 is a SIRIUS power contactor in Size S00, designed for switching motor loads and resistive loads in control panels. The coil is rated 24 VDC, and the contactor carries a rated current of 6 A at 24 V (resistive load). Screw-type terminals on the magnet coil simplify wiring with solid or stranded conductors from 0.5 to 4 mm². Mounting is via screw and snap-on onto a 35 mm DIN rail per DIN EN 60715, with a width of 45 mm, depth of 117 mm, and height of 58 mm. The mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward, giving flexibility in panel layout. Operating temperature range is -25 to +60 °C during operation, with storage from -55 to +80 °C. The contactor is rated for AC-1 switching at up to 1000 operations per hour, and AC-3 at up to 750 operations per hour. Mechanical life is typically 10,000,000 operations.
Panel Integration and Wiring
The 45 mm width fits standard DIN-rail spacing; the 117 mm depth leaves clearance for gland plates and backpanel wiring. Screw terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². No auxiliary switch is fitted on this variant. Clearance distances: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side. Arcing time is 10 to 15 ms at AC. These dimensions matter when grouping contactors in a panel — maintain the listed spacing to avoid arc flash between adjacent devices.
