The Siemens 5ST3674-0 is a professional-grade 1P+N connection busbar designed for electricians and panel builders who require streamlined, safe, and efficient electrical distribution. It excels at simplifying the wiring of compact 1P+N circuit breakers like the 5SV1, 5SV6, and 5SL60 series within the SENTRON system. A key caveat is that while it is designed for a fixed 12-module capacity, its specific 10mm² cross-section and 220mm length must be verified against your specific panel layout before installation to ensure a proper fit.

No, this specific model (5ST3674-0) is designed specifically for 1P+N compact circuit breakers.
Yes, it features full insulation to ensure touch protection and safety during operation.
Yes, the design allows for the installation of auxiliary switches even after the busbar has been mounted to the devices.
The busbar features a 10mm² cross-section; please refer to the technical datasheet for your specific load requirements and current rating limits.
Yes, the busbar can be cut to length to accommodate smaller numbers of modules within your panel.
Yes, it is a component of the Siemens SENTRON 5ST series.
Verify that you are using compatible 5SV/5SL60 series breakers and that there are no obstructions in the terminal housing.
Check that the busbar is fully seated in the terminal slots and that the terminal screws have been tightened to the recommended torque settings.
Use a sharp, fine-toothed hacksaw or a dedicated busbar cutter to prevent bending the copper and damaging the insulation.
To install, ensure all power is disconnected from the distribution board. Align the 5ST3674-0 busbar with the terminal inlets of your 5SV1, 5SV6, or 5SL60 series circuit breakers. If your rail has fewer than 12 units, carefully measure and cut the busbar to the required length, ensuring you maintain the integrity of the insulation. Always verify that no exposed copper is visible after cutting. Care should be taken to confirm that all terminal screws on the breakers are torqued to the manufacturer's specification once the busbar is inserted, ensuring optimal conductivity and preventing potential thermal issues.
