The 24 V coil holds at 0.85 of rated value and drops out at 1.85 times rated, giving a clean pick-up and drop-out margin for control circuits. Screw-type terminals accept solid or stranded conductors from 0.5 to 4 mm², with dual-wire capability up to 2x 2.5 mm². Rated for continuous operation from -25 to +60 °C ambient, with storage range of -55 to +80 °C. The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when panel layout forces an unconventional orientation. ## Switching Rates and Duty Cycles Maximum switching rates vary by duty: 1,000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor starting/running), and 250/h at AC-4 (plugging/inching). For a coupling contactor — typically used to isolate control signals or switch DC solenoids — the DC-13 rating at 24 V (10 A) is the headline figure; at 48 V the same contactor handles 2 A, and at 125 V it handles 0.9 A, so derate accordingly for higher-voltage DC circuits. ## Panel Integration — S00 Footprint The screw terminals accept 0.5 to 4 mm² solid or stranded, and two conductors per clamp are allowed (2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm²).","metaTitle":"Siemens 3RT2017-1SB42 SIRIUS Coupling Contactor, 24 VDC Coil","metaDescription":"Siemens 3RT2017-1SB42 SIRIUS coupling contactor, size S00, 24 VDC coil rated 10 A DC-13.
