Pick-up threshold is 0.85 x rated voltage (roughly 20.4 V), drop-out at 0.1 x rated (2.4 V). The auxiliary contact side switches 10 A at 24 V (AC-12), 6 A at 230 V, and 3 A at 400 V. If you're driving PLC outputs or small relays off the aux contacts, those numbers tell you the contact rating, not the coil draw. Side-by-side mounting is allowed with no derating gap — the S00 frame dissipates well enough that you can pack them tight. IP20 on the front and terminals — finger-safe, but not washdown-rated. ## Protection and coordination That's the selectivity headroom you need for the panel SCCR calculation — the fuse clears the fault before the contactor welds shut. ## Environmental compliance RoHS compliance date is listed as July 1, 2006 — covers the original EU RoHS directive. REACH and other substance restrictions are handled under Siemens' standard SIRIUS declaration.","metaTitle":"Siemens 3RT1316-2BB40 SIRIUS Power Contactor, S00, 4NO, 24 V","metaDescription":"Siemens SIRIUS 3RT1316-2BB40 power contactor, size S00, 4 NO main contacts, 24 VDC coil, spring-loaded terminals.

The 3RT1316-2BB40 has 4 NO main contacts and a 24 V DC coil; the 3RT1015-1BB42 has a different contact configuration and coil voltage. Check the contact arrangement and coil supply before swapping — the rail position and wireway clearance are identical."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1316-2BB40","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1316-2BB40 when reusing this data.
