Siemens SIRIUS 3RT2017-2LB42-0LA0 Power Contactor — 24 V DC Coil, Size S00, Spring-Type Terminals
The Siemens SIRIUS 3RT2017-2LB42-0LA0 is a size S00 power contactor with a 24 V DC coil and spring-type terminals, designed for screw and snap-on mounting onto 35 mm DIN rail per DIN EN 60715. Rated operational current at 24 V DC is 10 A. The 45 mm width and 70 mm height fit standard panel layouts, with a depth of 121 mm that clears most enclosure backplates.
Mounting and Clearance
Mounts on 35 mm DIN rail — screw or snap-on — per DIN EN 60715. Clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward.
Terminal and Wiring Data
Solid conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), 2x 4 mm²; solid or stranded: 2x (0.5–4 mm²). The coil connection uses spring-type terminals, reducing wiring time and eliminating screw torque checks.
