It's a spring-type terminal unit — no screwdriver needed for the power wiring, which speeds up panel assembly and field swaps. The coil pulls in at 24 VDC nominal, and the contactor is rated for 10 A at 24 V, 2 A at 48 V, 0.9 A at 125 V, and 0.3 A at 220 V DC, so it covers a range of DC control and small-load switching duties.
The S0 footprint (45 mm wide, 102 mm high, 107 mm deep) is a standard Siemens size that matches a wide range of overload relays and accessories.
Switching performance and conductor range
Maximum operating rates: 1,000 cycles/hour at AC-1, 750 at AC-2 and AC-3, 250 at AC-4. Arcing time is 10 ms. The main contact spring-type terminals accept solid or stranded conductors from 1 to 10 mm², or 2x (0.5 to 2.5 mm²) for parallel wiring.
