The Bemko A19-BBM-3F is a professional-grade 3-phase U-type busbar engineered for efficient and reliable electrical distribution within modular switchgear systems. Designed to accommodate up to 54 modules, this busbar provides a robust solution for connecting circuit breakers and various DIN-rail mounted devices. Its 10mm2 cross-section ensures optimal conductivity, while the U-type design facilitates a secure and stable connection, contributing to a clean and well-organized electrical panel layout suitable for both industrial and residential power distribution.
Advantages
The primary advantage of this busbar is its ability to significantly reduce installation time and complexity by eliminating the need for individual jumper wires between circuit breakers. By providing a solid, continuous conductive path, it minimizes the risk of loose connections and overheating, which are common issues in traditional wiring methods. The durable construction ensures long-term reliability, while the standardized design allows for seamless integration into existing electrical distribution boards, resulting in a professional and safe installation environment.
Suitable for
- Connecting multiple 3-phase circuit breakers in distribution boards
- Industrial electrical panel assembly
- Residential power distribution systems
- Modular switchgear configurations
When it may not be suitable
This busbar is specifically designed for 3-phase systems and is not compatible with single-phase configurations or applications requiring different phase arrangements. It is also not suitable for installations where the total current load exceeds the thermal capacity of a 10mm2 conductor.
Key specifications
- Phase configuration: 3-phase
- Type: U-type
- Cross-section: 10mm2
- Capacity: 54 modules
- Mounting: DIN-rail compatible devices
How to use
To install the busbar, first ensure that the main power supply to the distribution board is completely disconnected. Measure the required length for your specific configuration and cut the busbar if necessary, ensuring that the ends are properly insulated with end caps to prevent accidental contact. Align the U-type prongs with the terminals of the circuit breakers or modular devices mounted on the DIN rail. Insert the prongs firmly into the terminals and tighten the terminal screws securely to ensure a solid electrical connection. Verify that all connections are tight and that the busbar is correctly seated before restoring power.
What to consider before purchase
- Verify that your circuit breakers are compatible with U-type busbar connections
- Ensure the 10mm2 cross-section is sufficient for your total circuit load
- Check the physical space in your distribution board to accommodate the 54-module length
- Confirm that your system is a 3-phase installation
Usage recommendations: Always use appropriate personal protective equipment during installation and ensure that all electrical work complies with local safety regulations and standards. It is recommended to use end caps to protect exposed ends of the busbar.
