The DC coil draws 4 W for both pickup and hold, so the control transformer or DC supply needs to budget that continuous load per contactor.
DC switching — what the ratings mean
Unlike AC ratings, DC switching is voltage-limited by arc extinction. This contactor carries a full 10 A at 24 V DC, but that drops to 0.26 A at 600 V DC — the arc energy at higher DC voltages requires derating. Intermediate points: 4.7 A at 60 V DC, 3 A at 110 V DC, 1.2 A at 220 V DC, 0.5 A at 440 V DC, and 0.26 A at 600 V DC.
The S00 frame size and 4 NO contact configuration are shared with other SIRIUS aux contactors; the deciding factor for this order code is the DC coil voltage (not explicitly listed in the available specs) and the specific DC switching curve above.
Environmental and mounting notes
Terminal capacity accepts 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² solid or stranded — spring-cage or screw terminals depending on variant, but this order code uses screw-type.
