DBBS Range
The DBBS range offers a flexible solution for small power distribution applications.
The DBBS range is capable of Icw ratings of up to 50 kA/1 s.
They offer easy connection to moulded case circuit breakers. The intelligent design accommodates 20, 25, 30×10 mm, and 20, 25×5 mm conductors in one support. There is a 3 phase and a 3 phase + neutral version available.
- Up to 50 kA/1 s fault rating
- Suitable for 5 conductor sizes
