SIRIUS 3RT1015-2BE41 — 24 VDC Coil Power Contactor, Size S00
The Siemens 3RT1015-2BE41 is a SIRIUS power contactor in size S00, built for switching motor loads and resistive circuits in control panels. It mounts via screw and snap-on onto a 35 mm standard mounting rail per DIN EN 50022 — that's the same DIN rail every panel builder knows. The main circuit uses spring-loaded terminals, accepting 2x (0.25... 2.5 mm²) solid or stranded wire, so no screwdriver needed for the power connections. Rated operational current is 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. For motor duty at AC-2 at 400 V it's rated 3 kW; at AC-4 at 400 V it delivers 6.5 A. The 24 VDC coil draws 3.3 W holding power — a steady, low draw that keeps the panel power supply budget predictable.
Panel Fit and Integration
At 45 mm wide and 73 mm deep, this contactor fits a standard 45 mm slot on the DIN rail. Side-by-side mounting is allowed, so you can pack multiple units without spacing gaps — useful when the enclosure fill factor is tight. IP20 on the front and terminals means it's protected against finger contact but not washdown; keep it inside a closed panel. Operating temperature range is -25 to +60 °C, with a maximum operating altitude of 2 000 m. Pollution degree 3 suits industrial environments with conductive dust or occasional condensation.
Coordination and Protection
For type of coordination 2 (no damage to the contactor under short-circuit), the required upstream fuse is gL/gG 20 A. For type 1 coordination (contactor may need replacement after fault), the fuse can be 35 A. That gives the panel designer a clear choice between protection level and fuse size.
