The screw-type terminals on the magnet coil accept solid or stranded conductors from 0.5 mm² up to 4 mm², with double-wire capability for daisy-chaining control wiring.
The 45 mm width and 58 mm height (73 mm depth) fit the S00 frame footprint, which is the smallest in the SIRIUS contactor family — useful when you are packing multiple contactors into a shallow enclosure or a crowded DIN rail section. The mechanical service life is typical for the class at 30,000,000 operations, but the electrical endurance depends heavily on the duty category: at AC-1 (resistive loads) you can cycle up to 1,000 operations per hour, while AC-4 (plugging/reversing) drops to 250 per hour. For AC-3 motor switching, the 750 ops/h ceiling means this contactor handles frequent start/stop cycles on conveyors or pump motors without overheating the arc chamber. The switching capacity table tells you what the contactor can break at different control voltages — a critical detail when you are using it in a 24 VDC control circuit (10 A rated) versus a 400 VAC motor circuit (3 A rated). That 3 A at 400 V is the AC-15 control-circuit rating, not the motor full-load current; for motor switching you would reference the AC-3 rating which is higher. The 0.75 hp at 230 V gives a quick reference for small single-phase motor loads.
Mounting position is standing on a horizontal surface, with clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side. That 6 mm side gap is the one that catches people out — if you are laying out a row of contactors, you need that clearance for heat dissipation and arc flash containment. The operating temperature range is -25 to +40 °C, with storage down to -55 °C, so it is fine for unheated plant rooms or seasonal shutdowns provided the ambient stays within the operating band during running.
