The S0 frame is the bread-and-butter size for this class — fits a 45 mm wide slot on the DIN rail and handles the bulk of 3–7.5 kW motor duty in 400 V plants.
The 60 °C ceiling is standard for a panel-mounted contactor — if your enclosure gets hotter than that from drive heat or solar load, you'll need to derate or move it to a cooler zone. That's a lot of cycles — for a conveyor line cycling once every 10 seconds, that's about 3 years of continuous running before the contacts wear out. The main contact rating is unspecified here, but the S0 frame typically carries 9–12 A in AC-3 duty; the screw-type coil terminals accept solid or stranded wire from 1 to 10 mm², which is the standard range for this frame. No auxiliary switch block is fitted. If your circuit needs feedback contacts for a PLC input or status lamp, you'll need to add a side-mount auxiliary block. The contactor is designed for that — the S0 frame accepts standard SIRIUS auxiliary switch blocks that snap onto the side.
