It carries an AC-2 rating of 11 kW at 400 V for slip-ring motors and an AC-4 rating of 15.5 A at 400 V for reversing or inching duty — the AC-4 figure governs the real thermal stress during plugging or jogging cycles, not the steady-state AC-1 number. The magnet coil pulls 5.4 W on pickup and holds at the same 5.4 W DC, so there is no power-drop after closing — verify your 24 VDC supply can sustain that continuous draw across all contactors in the panel.
The S0 footprint measures 65 mm wide by 85 mm tall by 101 mm deep — the 101 mm depth is the dimension that matters for enclosure depth clearance, especially if a gland plate or door-mounted device sits behind the contactor.
Fuse coordination and wiring
The screw terminals accept 2x (0.25–2.5 mm²) solid or 2x (1–2.5 mm²) stranded, with a maximum of 2x 10 mm² or a single 8 AWG. Strip length and torque values follow standard Siemens terminal practice — no special tooling needed.
