What it is and what it does
The Siemens SIRIUS 3RT1317-2AN60 is a power contactor in size S00, designed for switching motor loads in control panels. It carries 4 normally-open main contacts and is rated for 5.5 kW at AC-2 duty at 400 V, meaning it handles moderate motor loads like pumps or conveyors without excessive contact wear. The main circuit uses spring-loaded terminals, accepting 2x (0.25... 2.5 mm²) solid or stranded wire — no screw torque check needed, which speeds panel wiring and reduces loose-connection callbacks.
Mounting and integration
Mounts via screw or snap-on onto a 35 mm standard mounting rail per DIN EN 50022. At 45 mm wide, it fits a standard DIN-rail footprint; side-by-side mounting is allowed, so you can gang multiple contactors without extra spacing. Front and terminal protection is IP20 — safe for finger contact inside an enclosure but not for washdown areas. Operating temperature range is -25 to +60 °C, which covers most indoor panel environments.
