SIRIUS Size S0 Power Contactor for 24 VDC Control
The Siemens 3RT2026-1BG40 is a SIRIUS-brand power contactor in the Size S0 frame, designed for switching motor and resistive loads in industrial control panels. It carries a 24 VDC coil rated at 10 A. Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with mounting positions allowing ±180° rotation on vertical surfaces and ±22.5° tilt forward/backward. The 45 mm width and 85 mm height fit standard panel layouts, with 10 mm clearance needed above and below, 6 mm at the sides. Operating temperature range is -25 to +60 °C; storage range -55 to +80 °C. The screw-type coil terminals accept solid or stranded wire from 1 to 10 mm², with auxiliary switch contacts rated for 125 V at 0.9 A.
Switching Duty and Mechanical Life
Rated for 1,000,000 operations at AC-1 (resistive), 750,000 at AC-2 and AC-3 (motor starting/running), and 250,000 at AC-4 (plugging/inching). Mechanical life is 10,000,000 cycles typical. The arcing time is 10 ms.
