Original Factory Bus Parts New Central Control Box Made of Plastic for Kinglong Zhongtong Yutong Bus Parts Higer Golden Dragon Ankai

The Central Control Box (CCB) is a critical electrical management and distribution unit used primarily in large commercial vehicles, especially Chinese-made buses such as Yutong, King Long, Higer, Zhongtong, and Golden Dragon. It serves as the central hub for managing multiple electrical circuits—including lighting systems, door controls, air conditioning, wipers, instrument clusters, and auxiliary power networks.

Designed to replace traditional fuse-and-relay panels, the modern Central Control Box integrates advanced electronic protection, relay switching, signal processing, and sometimes CAN bus communication into a single compact module. This enhances system reliability, reduces wiring complexity, and improves fault diagnosis capabilities. The CCB ensures safe and efficient power distribution while protecting sensitive components from overloads, short circuits, and voltage spikes.
