Siemens SIRIUS 3RT1016-1DB41-ZX95 is a size S00 power contactor with a 24 V DC coil, rated for motor loads up to 5.5 kW at 690 V. The front is IP20, so it's fine for enclosed panels but not washdown areas.
The 24 V DC coil picks up at 85% of rated voltage (about 20.4 V) and holds at 110% (26.4 V), with a constant 3.3 W draw closing and holding — no AC inrush to worry about on your DC supply. Switching capacity: 10 A at AC-12 (resistive loads), 6 A at 230 V, 3 A at 400 V, and 4.5 kW at 500 V or 5.5 kW at 690 V for motor duty. For AC-4 (frequent reversing or inching) at 400 V it's rated 8.5 A. The auxiliary contact is a single instantaneous N/O. The varistor surge suppressor is built in across the coil — no external snubber needed for standard inductive loads.
Size S00 footprint: 45 mm wide, 57.5 mm tall, 111 mm deep. Wire range: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid/stranded — spring-cage not available, these are screw terminals.
The altitude rating is 2,000 m max; above that, derate per IEC 60947.
