Spring-type terminals accept solid conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), 2x 4 mm², and solid or stranded 2x (0.5...4 mm²). No screwdriver torque needed — strip, insert, done. Compared to the 3RT2015-1BW42, the 3RT2017-2LF42-0LA0 steps up from a 24 V DC coil to a 110 V DC coil and adds spring-type terminals instead of screw terminals — a direct swap in the same S00 footprint if your control voltage and termination preference align. No rewiring of the DIN rail or busbar needed. Mechanical life typical 30,000,000 operations. Arcing time 10...15 ms. Includes an auxiliary switch. Suitable for motor loads up to 2 hp at 230 V AC.","metaTitle":"Siemens SIRIUS 3RT2017-2LF42-0LA0 Power Contactor, 110 V DC","metaDescription":"Siemens SIRIUS 3RT2017-2LF42-0LA0 power contactor, size S00, 110 V DC coil, spring-type terminals, 11 A at 480/600 V AC.
