FAQs

 

What is the purpose of the CBB-2 Busbar?

The CBB-2 Busbar is used to distribute power efficiently across multiple circuit breakers or modular devices, simplifying wiring and enhancing safety in low-voltage panels. 

 

What configurations are available?

It comes in 1P, 2P, 3P, and 4P configurations, compatible with CHINT NB1 and NB2 modular devices. You can select from 10 mm² or 16 mm² cross-sections, depending on current load requirements. 

 

What is the difference between U-type and Pin-type Busbars?

U-type Busbars use forked terminals, ideal for devices with U-shaped input terminals.

Pin-type Busbars use solid pins, suitable for devices with pin entry terminals.

Both ensure secure, low-resistance connections. 

 

What environmental conditions can the CBB-2 operate in?

It operates reliably between −5 °C and +40 °C, at altitudes up to 2000 m, and with humidity up to 90 % at 20 °C, making it suitable for most indoor installations. 

 

Is the CBB-2 compatible with CHINT circuit breakers?

Yes. It’s designed to perfectly integrate with CHINT NB1, NB2, and NB3 series Miniature Circuit Breakers (MCBs) and related modular protection devices.
