Product details

It's the first laterally mountable design in this frame, meaning it sits alongside the contactor without stealing the top slot. At 10 mm wide, it's the narrowest add-on in the S00 family; you can stack several across the face of a 45 mm contactor without blowing past the panel's DIN-rail envelope. Rated operational current hits 6 A at both 24 V and 230 V, and it carries a mirror contact per IEC 60947-4-1 — that's the feedback contact for safety circuits, so it mechanically tracks the main poles.

Ratings that matter for the panel

The AC-15 rating at 690 V is 1 A — that's the inductive load curve for contactor coils and solenoid valves, the typical use for an auxiliary on a motor starter. The 6 kV surge voltage resistance means it's good for 400 V line-to-line panels without extra suppression. The mirror contact feature (IEC 60947-4-1) is what lets you wire it into the safety chain without a separate feedback module.

Snap-on mounting to the contactor — no tools, no DIN-rail clip. The 10 mm width means it fits between the contactor body and the next device on the rail; depth is 66 mm, height 57.4 mm. Wire range accepts 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, or AWG 20-16 / 18-14.

Frequently asked questions

What is the width and depth of 3RH6911-1DA11?

Width is 10 mm, depth is 66 mm, height is 57.4 mm. The narrow profile lets you stack multiple auxiliary blocks on an S00 contactor without exceeding the DIN-rail envelope.

What compliance documentation does 3RH6911-1DA11 carry?

The part carries a mirror contact per IEC 60947-4-1, surge voltage resistance of 6 kV, and IP20 protection on the front. RoHS compliance date is noted as May 1, 2012. No UL or CSA listing is explicitly in the spec record.

Where can I buy 3RH6911-1DA11 and what is the price?

Sourced to order against an RFQ through independent distribution. Current pricing and availability are confirmed at quote time — submit an RFQ for a firm quote.

Will 3RH6911-1DA11 drop into a panel specified around 3RH6140-1BF40?

Both are SIRIUS auxiliary switches for S00 contactors, same snap-on mounting and 10 mm width. The 3RH6911-1DA11 is the current-production design; it should fit the same contactor face and wiring footprint without rewiring, though the 3RH6140-1BF40 may have different contact configuration or ratings — verify the NO/NC count against your schematic.
