At 45 mm wide, side-by-side mounting is allowed without extra spacing. Connections are via spring-loaded terminals on the main current circuit, accepting solid or stranded conductors 2x (0.25... 2.5 mm²). The auxiliary circuit uses the same terminal type, rated at 9 A per NC and per NO contact. No screwdriver torquing needed — spring-cage termination speeds up panel wiring and holds secure under vibration. Coil draws 5.1 VA at 50 Hz and operates on 400 V at 50 Hz or 400...440 V at 60 Hz. The 24 V rated coil variant (this order code) pulls 10 A at 24 V, with lower currents at higher voltages — 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V for the auxiliary contacts. Verify your control transformer sizing against these inrush values. Altitude rated to 2,000 m.
When sourcing against an RFQ, expect that this part is quoted to order through the Siemens SIRIUS program.
AC-1 maximum switching frequency is 1,000 1/h. For motor loads, AC-3 rating would govern; this unit's auxiliary contact ratings give the signal-switching envelope. Arcing time of 10...15 ms and AC switching times of 4...30 ms are typical for a contactor this size — fast enough for most PLC-driven sequences, but if your application requires <10 ms total break time, consider a semiconductor switch. The mechanical endurance of 30 million operations means it outlasts most panels it's installed in. IP20 on the front and at the terminals means finger-safe but not washdown-rated. Install inside a cabinet with at least IP54 enclosure for dusty or damp environments. The mounting position allows vertical surface mounting with +/-180° rotation and +/-30° tilt front-to-back — flexible for tight layouts.
