SIRIUS 3RT1015-1AK62-ZX95 — Size S00 Power Contactor, 24 VDC Coil
The Siemens 3RT1015-1AK62-ZX95 is a SIRIUS power contactor in the compact S00 frame, designed for switching motor loads and resistive circuits in control panels. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 50022, fitting into a 45 mm wide slot with a depth of 72 mm and height of 57.5 mm — a standard footprint for panel integration. The coil is rated for 24 VDC, and the contactor carries a rated operating current of 10 A at 24 V (AC-12), 6 A at 230 V, and 3 A at 400 V. For motor duty, it delivers 3 kW at 400 V in AC-2 service and 6.5 A in AC-4 at 400 V. At 690 V, the rated power reaches 4 kW. These ratings define the load it can switch within its thermal limits — the AC-4 figure is the one to check for reversing or plugging duty where the contactor makes and breaks full motor current.
Termination and Coordination
Main circuit connections use screw-type terminals accepting solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²). For type 2 coordination (no-weld), the required upstream fuse is gL/gG 20 A; for type 1 coordination, gL/gG 35 A. The front and terminal faces carry IP20 protection, and the unit is rated for pollution degree 3 environments. Side-by-side mounting is permitted with a 6 mm gap at the side. Operating temperature range is -25 to +60 °C during operation, with a maximum installation altitude of 2 000 m. The contactor's rated frequency is 50/60 Hz, with an operating voltage range of 0.85 to 1.1 times rated at 50 Hz and 0.8 to 1.1 at 60 Hz. Mechanical life is rated at 30 million cycles typical.
