Siemens 3RT2317-1BM40 — SIRIUS Size S00 Contactor, Screw Terminals
For resistive loads (AC-1), the same contactor carries 12 A at 400 V, useful for heater banks or lighting circuits. The screw-type terminals on both main and auxiliary circuits accept solid conductors from 0.5 to 4 mm² and stranded up to 2.5 mm², covering most panel wiring sizes without needing lug adapters. Mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position is flexible: ±180° rotation on a vertical surface, plus ±22.5° tilt forward/backward — useful when fitting into tight enclosures or angled subpanels. Side-by-side mounting is allowed, with a 6 mm gap to adjacent devices for cooling.
Listed as current-production (active lifecycle stage). No end-of-life notice or last-time-buy date is recorded. For BOM-freeze or PCN-watch scenarios, the S00 frame and screw-terminal format are stable across the SIRIUS generation — no imminent form-factor change expected.
Ratings and Environmental Limits
Rated insulation voltage is 220 V DC for the magnet coil (screw-terminal coil connection). The contactor's mechanical life is typical 30 million operations — a figure that reflects the S00 frame's duty cycle for high-switching applications like conveyor or pump cycling. Coil pick-up and drop-out: initial value 0.8 (80% of rated voltage for pick-up), full-scale value 1.1 (110% for hold). DC switching time (at coil) is 7–13 ms. These matter for sequencing interlocking or safety circuits where contactor dropout timing must be predictable.
RoHS compliant per substance prohibition date 10/01/2009. The SIRIUS series carries CE, UL, CSA, and IEC certifications (standard for the brand). Full compliance documentation — including RoHS, REACH, and IEC 60947-4-1 test reports — is available from Siemens upon request or through the product support portal.
