CHINT CBB‑211310 P+N connection comb busbar

The CHINT CBB‑211310 is a plug‑in comb busbar designed for the P+N (phase and neutral) connection across DIN‑rail mounted modular devices. It supports a 10 mm² copper cross‑section and is compatible with 18 mm width modules, enabling a reliable and quick connection of phase and neutral conductors in low‑voltage distribution panels.
Manufactured to handle a nominal voltage of 230/400 V and an impulse withstand voltage up to 4 kV, the CBB‑211310 is built to IEC‑compliant quality standards. It is constructed as a needle‑type busbar with a 1.5 mm thickness, suitable for use in environments with pollution degree 2 and ambient temperatures from –5 °C to +40 °C.
This product simplifies installation by bridging both phase and neutral conductors simultaneously, reducing wiring time and ensuring secure connections, ideal for residential or commercial electrical distribution boards.
