## Long description

The Siemens 5ST3733 is a high-quality 1-phase pin-type busbar engineered for the efficient and secure electrical connection of circuit breakers that feature an auxiliary contact. With a cross-section of 10mm² and a total length of 1016mm, this component is designed to facilitate professional power distribution in both residential and industrial modular electrical systems. Its robust construction ensures reliable conductivity, while the touch-safe design provides an essential layer of protection during the installation process.
Advantages
This busbar offers significant flexibility for electrical installers due to its cuttable design, allowing it to be customized to the specific dimensions of any distribution board. By utilizing this component, you can streamline the wiring process for miniature circuit breakers and residual current devices, significantly reducing the time required for assembly. The integration of auxiliary contact compatibility ensures that complex control and monitoring setups can be wired neatly and safely. Furthermore, the standardized touch protection minimizes the risk of accidental contact, adhering to high safety standards for electrical infrastructure.
Suitable for
Modular distribution boards in residential buildings
Industrial electrical control panels
Systems requiring miniature circuit breakers with auxiliary contacts
Residual current device installations
When it may not be suitable
This busbar is specifically designed for 1-phase systems and cannot be used for 3-phase power distribution. It is not suitable for applications requiring a cross-section larger than 10mm² or for installations where the specific pin-type connection interface is not compatible with the chosen circuit breakers.
Key specifications
Phase: 1-phase + auxiliary contact
Cross-section: 10mm²
Length: 1016mm
Type: Pin-type busbar
Customization: Cuttable to required length
Safety: Touch-safe design
How to use
To install the busbar, first measure the required length based on the number of circuit breakers in your distribution board. Cut the busbar carefully using appropriate tools, ensuring that no metal burrs remain. Once cut, align the pins with the terminals of the circuit breakers and auxiliary contacts. Insert the pins firmly into the terminals and tighten the screws to ensure a secure electrical connection. Verify that the busbar is fully seated and that the touch protection is intact before energizing the system.
What to consider before purchase
Ensure your circuit breakers are compatible with pin-type busbars
Verify that the 10mm² cross-section meets the current requirements of your circuit
Check if your specific installation requires end caps, as they are not included
Confirm the total length needed for your distribution board layout
Usage recommendations
Always ensure the power supply is completely disconnected before attempting to install or modify the busbar. Use appropriate personal protective equipment and follow local electrical codes and regulations during installation.
