The 10 A rating at 24 V DC is the coil inrush current, not the main contact rating; the main contacts are rated for motor duty (AC-3) and resistive loads (AC-1), though specific AC-3/AC-1 current values are not listed in this spec set. The Size S00 footprint (45 mm wide, 70 mm high, 121 mm deep) is the smallest SIRIUS contactor frame, suited for compact panels where space is tight. The contactor can be installed in any position, but the preferred orientation is standing on a horizontal mounting surface. Maintain 6 mm clearance at the sides and 10 mm above/below for arc flash and heat dissipation. Spring-type terminals on the coil side accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid conductors. For stranded wire, the range is 2x (0.5 to 4 mm²). This covers common control wiring sizes without needing ferrules, though ferrules are recommended for stranded in high-vibration environments.","metaTitle":"Siemens 3RT2017-2LB42-1LA0 SIRIUS Power Contactor, 24 V DC,","metaDescription":"Siemens SIRIUS power contactor 3RT2017-2LB42-1LA0, 24 V DC coil, 10 A at 24 V DC, Size S00, spring-type terminals, snap-on DIN rail.
