It is part of the SIRIUS modular system, which means it shares a common accessory platform and busbar system with other S0 devices. The 24 V DC coil is controlled via screw-type terminals, and the main contacts are rated for 16 to 8 A, making it suitable for smaller motor circuits up to about 4 kW at 400 V AC-3 duty.
The 45 mm width and 85 mm height fit the standard S0 footprint on a 35 mm DIN rail per DIN EN 60715. Wire capacity is 1 to 10 mm² for both solid and stranded conductors, with the screw terminals accepting two conductors per clamp (2x 0.5-1.5 mm² or 2x 0.75-2.5 mm²). That's enough for a 4 mm² motor feed and a 1.5 mm² control wire in the same terminal, which saves a terminal block row. Storage range extends to -55 to +80 °C, which matters if you're staging spares in a warehouse that isn't climate-controlled.
Switching frequency depends on the load: 1000 cycles/hour for AC-1 resistive loads, 750 cycles/hour for AC-2 and AC-3 motor loads, and 250 cycles/hour for AC-4 plugging or inching duty. If you're cycling a conveyor start/stop more than once every 5 seconds, you'll want to check the thermal derating.
