Product details

14-pole interconnect for SIRIUS motor starter assemblies

The 3RA6931-0A is a 14-pole connecting cable, 8 mm diameter, used to route control signals and auxiliary power between SIRIUS motor starter components — contactors, overload relays, and soft starters — within the same DIN-rail assembly. At 25 mm wide, it occupies one standard 18 mm DIN-rail spacing unit, so it fits into the same panel layout as the SIRIUS 3RA6 and 3RA7 series devices without crowding adjacent components.

Environmental limits and panel safety

Rated for operation from -20 to +60 °C with 10 to 90 % relative humidity, this cable handles the thermal range inside a ventilated industrial enclosure without derating. Storage and transport limits extend from -55 to +80 °C, so it tolerates warehouse and trucking extremes before installation. The front face carries IP20 finger-safe touch protection per IEC 60529, meaning the exposed connector surface meets the standard probe test — no live parts are accessible during maintenance with the panel door open.

Frequently asked questions

What is 3RA6931-0A's width and how does it mount?

Width is 25 mm, which corresponds to one standard 18 mm DIN-rail spacing unit. It snaps onto the DIN rail alongside SIRIUS motor starter components.

What temperature range can 3RA6931-0A handle during storage?

Storage temperature range is -55 to +80 °C, matching the transport range. Operating range is -20 to +60 °C.

Will 3RA6931-0A drop into a panel specified around 6ES7193-4CC30-0AA0?

No — those are different product classes. The 6ES7193-4CC30-0AA0 is a SIMATIC ET 200S bus module (15 mm wide, 43 mm deep), while the 3RA6931-0A is a SIRIUS motor starter connecting cable (25 mm wide). They serve different functions and are not mechanically interchangeable.
