SIRIUS S00 Power Contactor — 24 VDC Coil, Screw Terminals
The Siemens 3RT1015-1AX22-0VA2 is a SIRIUS-brand power contactor in the compact S00 frame size, designed for switching motor loads and resistive circuits in control panels. It uses a 24 VDC coil and terminates through screw-type terminals on both main and auxiliary circuits. Mounting is via screw fixing or snap-on onto 35 mm standard rail per DIN EN 50022, making it a drop-in fit for existing DIN-rail panel layouts. The 45 mm width, 57.5 mm height, and 72 mm depth keep panel density high. Rated operational current at AC-12 (resistive) reaches 10 A at 24 V. For motor switching, the AC-4 rating at 400 V is 6.5 A, and the AC-2 rating at 400 V delivers 3 kW. The coil holds across 0.8...1.1 x rated voltage at 50 Hz and 0.85...1.1 at 60 Hz. Mechanical endurance is typical 30 million switching cycles, supported by the pollution degree 3 rating for industrial environments. Ambient operation spans -25 to +60 °C, with a maximum altitude of 2000 m.
Termination and Wiring
Main current circuit terminals accept solid or stranded conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or max. 2x (0.75...4 mm²). AWG equivalents are 2x (20...16), 2x (18...14), and 1x 12. The screw terminals are rated IP20, matching the front protection class. For type of coordination 2, a gL/gG fuse of 20 A is required; for type of coordination 1, a 35 A gL/gG fuse applies. Side-by-side mounting is permitted without derating, with a 6 mm clearance to adjacent devices.
Switching Capacity Across Voltages
The contactor's switching capacity varies with voltage and duty: at 60 V DC it handles 2 A, at 110 V DC 1 A, at 220 V DC 0.3 A, and at 230 V AC 6 A. At 400 V AC the rated operational power is 3 kW (AC-2) or 4 kW at 690 V AC.
