Siemens 8US1211-4TM00 is a SENTRON busbar system device adapter designed for 60 mm busbar center-to-center spacing. It provides a practical interface for assembling a SIRIUS circuit breaker, size S3 (up to 100 A), onto a 60 mm system using busbar thicknesses from 5 to 10 mm with TT profile support. The adapter is intended for applications in the 480–690 V operating range and features an AWG 4 electrical connection. With an overall length/height of 182 mm and a compact 60 mm depth, it helps create a neat, space-efficient distribution layout in control panels and switchboards.
What does this device adapter do in a busbar system?
It provides a mechanical and electrical interface between a 60 mm center-to-center busbar system and compatible protection devices, allowing a circuit breaker to be mounted and connected to the busbars in a standardized way.
Which busbar system spacing is it designed for?
It is designed for busbar systems with 60 mm center-to-center spacing.
Which circuit breaker size is it intended to be assembled with?
It is intended for use with Siemens SIRIUS circuit breakers, size S3, up to 100 A (as an assembly application).
What operating voltage range is it suitable for?
The specified application/operating range is 480 to 690 V.
What busbar thickness range does it accommodate?
It is intended for busbars with a minimum thickness of 5 mm and is commonly used with 5 mm and 10 mm rail thicknesses (with TT profile system compatibility as specified by Siemens for this adapter style).
What are the main physical dimensions for panel layout planning?
Key dimensions are: length/height 182 mm, depth 60 mm, and a stated overall width of 72 mm for the adapter system. The adapter body width is specified as 54 mm.
How is the electrical connection specified?
The electrical connection is specified as AWG 4.
Is this considered a complete switching device?
No. It is an accessory (device adapter) that forms part of a busbar mounting/connection solution; the protective switching function is provided by the circuit breaker assembled to it.
What is the typical use case in industrial panels?
It is typically used in low-voltage distribution assemblies to mount and connect SIRIUS S3 circuit breakers onto a 60 mm busbar system, helping create compact, repeatable feeder arrangements.
What is the approximate net weight?
The net weight is approximately 476 g.
Does it have conformity documentation or approvals?
It is supplied as a SENTRON accessory with a Declaration of Conformity, and it appears in recognized certification listings for busbar adapter components (model 8US1211-4TM00).
What should I check to confirm compatibility before ordering?
Confirm the busbar system is 60 mm spacing, the busbar thickness meets the minimum requirement, the intended breaker is a SIRIUS size S3 device (up to 100 A application), and that the available panel space fits the 182 mm length and 60 mm depth envelope.
- Adapting SENTRON busbar assemblies with 60 mm busbar spacing to accept Siemens SIRIUS circuit breakers, size S3 (up to 100 A)
- Building compact power distribution sections in industrial control panels where 480–690 V busbar systems are used
- Adding or modifying outgoing feeder connections on busbar rails during panel expansions or retrofits
- Standardising circuit breaker mounting on mixed busbar thicknesses (5 mm and 10 mm) using a consistent adapter format
- Creating modular distribution layouts where multiple protective devices need repeatable positioning and alignment on the busbar system
- Integrating circuit breaker protection into machine or process skids that use busbar-based internal power distribution
- Streamlining assembly of switchboard sub-sections by providing a dedicated device adapter length (182 mm) for S3 breaker installation
- Supporting orderly panel wiring by providing an AWG 4 connection interface for robust power terminations
