It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when you're squeezing it into a crowded cement plant panel where the enclosure orientation is fixed but the contactor needs to sit at an angle for access.
Wiring and terminal details
Main contact terminals accept solid or stranded wire: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) for the auxiliary circuit, and 1 to 10 mm² stranded for the power path. The magnet coil uses screw-type terminals — no special crimp tool needed, just a standard screwdriver. That's tight enough for a 60 mm wide device in a standard enclosure, but watch the forward clearance if the panel door has a deep component on the swing.
The S0 frame size is the mechanical envelope that governs panel layout and busbar spacing. At 60 mm wide, 85 mm tall, 97 mm deep, it fits the standard S0 footprint shared across the SIRIUS contactor family — so a panel originally laid out for a different S0 contactor (like the 3RT2024 series) can accept this unit without re-drilling the DIN rail or re-routing the main power wires, provided the coil voltage matches.
