Product details

Siemens 3RT2517-1BW40 — SIRIUS Contactor, Size S00

Rated for a 24 V DC coil, the auxiliary contact block carries 10 A at 24 V and 230 V AC, 2 A at 48 V and 60 V DC, and derates to 0.1 A at 600 V AC — covering signal feedback and interlocking needs across common control voltages.

Snap-on to 35 mm DIN rail per DIN EN 50022; screw terminals for main and auxiliary circuits accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded wire. Dimensions: 57.5 mm height, 45 mm width, 73 mm depth — compact enough for high-density panel layouts.
