## Long description

The Siemens 5ST3705 is a professional-grade 2-phase pin-type busbar engineered for efficient and reliable power distribution within electrical installations. Measuring 1016mm in length with a 16mm² cross-section, this component is designed to streamline the connection process between miniature circuit breakers, ensuring a stable and secure electrical path in both residential and industrial distribution boards.
Advantages
This busbar offers significant time savings during the assembly of electrical panels by eliminating the need for complex individual wiring between circuit breakers. Its robust construction ensures high conductivity and long-term durability, while the pin-type design provides a firm and reliable contact. By utilizing this standardized component, installers can achieve a cleaner, more organized, and safer wiring configuration that meets professional electrical standards.
Suitable for
Connecting miniature circuit breakers in distribution boards
Residential electrical panel installations
Industrial power distribution systems
Projects requiring rapid and secure multi-phase wiring
When it may not be suitable
This busbar is specifically designed for 2-phase configurations and cannot be used in 3-phase or single-phase systems requiring different terminal layouts. It is also not suitable for applications where the current load exceeds the capacity of a 16mm² conductor or where the physical dimensions of the distribution board do not accommodate a 1016mm length.
Key specifications
Phase configuration: 2-phase
Cross-section: 16mm²
Length: 1016mm
Connection type: Pin-type
How to use
To install the busbar, first ensure that the power supply to the distribution board is completely disconnected. Cut the busbar to the required length if necessary, ensuring that the ends are properly insulated. Insert the pins into the corresponding terminals of the miniature circuit breakers. Tighten the terminal screws securely to ensure a low-resistance connection. Verify that all connections are firm and that no exposed metal parts could cause a short circuit before restoring power.
What to consider before purchase
Verify the phase requirements of your electrical system
Measure the available space in your distribution board
Ensure compatibility with the terminal type of your circuit breakers
Check if the 16mm² cross-section is sufficient for your total current load
Usage recommendations
Always adhere to local electrical codes and safety regulations when installing power distribution components. It is recommended to use end caps to cover exposed ends of the busbar to prevent accidental contact.
