## Long description

The Siemens 5ST3730 is a professional-grade 1-phase pin-type busbar engineered for reliable electrical distribution within modular installations. Designed with a 10 mm² cross-section and a total length of 214 mm, this component provides a robust solution for connecting up to 12 modules, such as circuit breakers or residual current devices. Manufactured in Germany, this busbar ensures high standards of safety and electrical conductivity, making it an essential element for organized and efficient electrical panel assembly.
Advantages
This busbar offers a significant reduction in wiring complexity by eliminating the need for individual jumpers between modular devices. Its pin-type design ensures a secure and stable connection, while the ability to cut the bar to the required length provides maximum flexibility during installation. The inclusion of end caps enhances safety by preventing accidental contact with live parts, ensuring a touch-safe environment within the distribution board.
Suitable for
Professional electrical panel assembly
Connecting modular circuit breakers
Distribution of power in residential and commercial electrical cabinets
Systems requiring 1-phase electrical supply
When it may not be suitable
This busbar is specifically designed for 1-phase systems and cannot be used for 3-phase installations. It is also not suitable for applications requiring a cross-section larger than 10 mm² or for devices that do not support standard pin-type busbar connections.
Key specifications
Phase: 1-phase
Cross-section: 10 mm²
Length: 214 mm
Capacity: 12 modules
Connection type: Pin-type
Safety: Touch-safe design
How to use
To install the busbar, first measure the required length based on the number of modular devices in your panel. If necessary, cut the busbar to size using appropriate tools and ensure the edges are clean. Slide the busbar into the terminals of the modular devices, ensuring that each pin is fully seated. Once positioned, secure the connections by tightening the terminal screws on the devices. Finally, attach the provided end caps to the open ends of the busbar to ensure the installation is touch-safe.
What to consider before purchase
Verify that your modular devices support pin-type busbar connections.
Ensure the 10 mm² cross-section is sufficient for your circuit's current load.
Confirm that the 1-phase configuration matches your electrical system requirements.
Check the total number of modules to ensure the 214 mm length is adequate.
Usage recommendations: Always ensure the power supply is completely disconnected before performing any installation or maintenance work on electrical panels. Use appropriate personal protective equipment and follow local electrical regulations during assembly.
