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.
