No screw torque to check — just strip to 8 mm and push in. ## Coil and control Coil draws 3.3 W DC both closing and holding — no power drop-off after pickup, so the control transformer or DC supply needs to sustain that continuously. Pickup threshold is 0.85 x rated voltage (93.5 V DC), dropout at 0.1 x rated (11 V DC). ## Load switching and protection Rated operational current at AC-12 (resistive) is 10 A maximum. For motor loads, AC-2 at 400 V gives 4 kW; AC-4 at 400 V gives 8.5 A. At 500 V it handles 4.5 kW, at 690 V it handles 5.5 kW — those are the motor ratings for a standard squirrel-cage induction motor. For short-circuit protection, type 2 coordination requires a gL/gG fuse rated 20 A; type 1 coordination allows 35 A. RoHS compliance date is 01.07.2006.","metaTitle":"Siemens 3RT1016-2BF41 SIRIUS S00 Contactor, 110 V Coil","metaDescription":"Siemens SIRIUS 3RT1016-2BF41 power contactor, size S00, 110 V DC coil, spring-loaded terminals, 4 kW at AC-2 400 V.

It shares the same mounting footprint and terminal style, but the coil voltage differs, and the 3RT1016-2BF41 carries higher AC-4 current ratings. Panel drop-in is possible only if the coil voltage and load current match the lower-rated sibling."},{"question":"What is the listed depth of the 3RT1016-2BF41?","answer":"Depth is 73 mm, width 45 mm, height 60 mm. The S00 frame is one of the smallest contactor sizes, leaving room for auxiliary blocks or overload relays on the same DIN rail."},{"question":"What wire sizes does the spring-loaded terminal accept?","answer":"It accepts 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). No ferrule required for stranded, but a ferrule helps maintain shape in high-vibration panels."},{"question":"Will 3RT1016-2BF41 drop into a panel specified for 3RT1015-1BB42?","answer":"Mechanically yes — same S00 footprint, same DIN rail clip, same spring-loaded terminal layout. Electrically check the coil voltage: 3RT1016-2BF41 is 110 V DC, while 3RT1015-1BB42 is 24 V DC. Also verify load current — the 3RT1016-2BF41 has higher AC-4 ratings (8.5 A vs lower on the sibling)."},{"question":"What compliance documentation is available for this contactor?","answer":"RoHS compliance date is 01.07.2006. The product carries IEC 60947-4-1 ratings for contactors and motor starters. UL/CSA listing is typical for SIRIUS S00 devices but not confirmed in this specific listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1016-2BF41","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/3RT1016-2BF41 when reusing this data.
