The coil draws 1.4 W both on pick-up and hold, so the control transformer can be sized tightly; pick-up threshold is 0.85 (20.4 V) and drop-out is 1.85 (44.4 V) — meaning it will hold in on a sagging 24 V bus but drop cleanly if the supply collapses. ## Motor duty and auxiliary contacts Rated motor power in AC-3 duty: 4.5 kW at 500 V and 5.5 kW at 690 V. For the less common AC-2 duty (slip-ring motors, soft-start bypass) it delivers 4 kW at 400 V. In AC-4 (plugging, inching) it handles 8.5 A at 400 V. The built-in surge suppressor uses a diode across the coil — polarity-sensitive, so verify DC supply orientation before wiring. Auxiliary contact ratings are given across multiple voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 0.3 A at 220 V — enough for a PLC input or a small pilot light. Side-by-side mounting is allowed with zero spacing — the 45 mm width per pole means a three-contactor group fits in 135 mm of rail. Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). Strip length is not given in the listing, but standard for spring-cage is 8-10 mm. IP20 on the front and on the terminals — fine for a closed panel, not for washdown.","metaTitle":"Siemens 3RT1016-2VB42 SIRIUS Power Contactor, 24 VDC, Size S","metaDescription":"Siemens 3RT1016-2VB42 SIRIUS power contactor, 24 VDC coil, spring-loaded terminals, IP20, size S00.

If your panel is wired with ring or fork terminals, the 2AP02 drops in without rewiring the rail; if you already have spring-cage tooling, stick with the 2VB42."},{"question":"What is the depth of 3RT1016-2VB42?","answer":"The depth is 73 mm. Combined with the 45 mm width and 60 mm height, it fits standard 100 mm deep enclosures with room for wiring ducts."},{"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). Two conductors per clamp are allowed, which helps when daisy-chaining control power."},{"question":"Will 3RT1016-2VB42 drop into a panel specified for 3RT1016-2AP02 without rewiring?","answer":"Yes, the mounting footprint and coil voltage are identical — both are size S00 on 35 mm DIN rail with a 24 VDC coil. The only difference is the terminal type: spring-loaded on the 2VB42 versus screw on the 2AP02. If the existing wiring uses ferrules or solid wire, the spring clamp works fine; if it uses ring terminals, you will need to trim them or switch to the screw-terminal variant."},{"question":"What compliance documentation does Siemens provide for 3RT1016-2VB42?","answer":"As a SIRIUS component, it is typically CE-marked and designed to IEC/EN 60947-4-1. For specific UL, CSA, or RoHS/REACH declarations, refer to the nameplate or Siemens' online support portal — the evidence does not list individual marks, but the product is intended for global industrial panels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1016-2VB42","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/3RT1016-2VB42 when reusing this data.
