The S0 frame size (45 mm wide, 85 mm tall, 107 mm deep) is the standard building block for motor loads up to roughly 5.5 kW at 400 V in AC-3 duty.
The main contactor is rated for 1 000 operations per hour in AC-1 (resistive) duty, 750/h in AC-2 and AC-3 (motor start/run), and 250/h in AC-4 (plugging/reversing). The AC-3e rating also sits at 750/h, matching the standard motor-switching tempo for conveyor, pump, and fan applications. The built-in auxiliary switch (1 N/O + 1 N/C, wired as 16-8 on the main contact block) carries 10 A at 24 VDC, 2 A at 48 VDC, 2 A at 60 VDC, 1 A at 110 VDC, 0.9 A at 125 VDC, 0.3 A at 220 VDC, and 3 A at 400 VAC. That DC curve matters if you are switching a PLC input or a DC brake coil — the 24 V rating is generous, but the drop-off above 60 V is steep.
Arcing time is 10 ms, and the DC dropout delay (coil off to contacts open) is 15-18 ms. That is fast enough for most safety circuits but worth noting if you are coordinating with a downstream contactor that has a longer dropout.
