Siemens SIRIUS 3RT2026-2BB40-ZX95 — Power Contactor, Size S0, 24 VDC Coil
The contactor mounts on a 35 mm DIN rail per DIN EN 60715, using either the screw or snap-on method, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward or backward, which gives flexibility in tight enclosures.
The contactor is rated for 10 A at 24 V, but the switching capacity varies with voltage: 2 A at 48 V or 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The DC operating time is 15 to 18 ms, and arcing time is 10 ms — fast enough for most control schemes but verify your PLC cycle time if you're sequencing multiple contactors.
Spring-type terminals accept solid or stranded conductors from 1 to 10 mm², and for auxiliary contacts, 2x (0.5 to 2.5 mm²) solid or stranded. The main contact rating range is 18 to 8 A — that's the thermal continuous current range for the main poles, so size your overload relay accordingly.
