Special Features

  • 【Red and Black Bus Bar】 The red power distribution block is positive, while the black power distribution block is negative. Compared to traditional multi-cable wiring, a 300A bus bar makes the layout of an electrical system cleaner and more aesthetically pleasing. Additionally, the compact structure of bus bars allows for more effective space utilization, especially in distribution cabinets or electrical shafts with limited space. Using bus bars can save space and simplify the installation and wiring of other equipment.
  • 【High Current Carrying Capacity】 The 300A bus bar's rated current can safely and effectively carry large currents, which is crucial for systems that require the transmission of high-power electrical energy. In such scenarios, devices may demand significant power, and the 300A bus bar can meet the power requirements of high-load devices, ensuring stable power transmission.
  • 【Low resistance - Brass Bus Material】 The bus bar is made of high-quality conductive copper, which has low resistance. This low resistance reduces the loss of electrical energy during transmission, improving efficiency and minimizing heat generation in the bus bar itself, thereby supporting the stable operation of the system.
  • 【Easy to Install and Expand】 The structure of the bus bar is simple and easy to install. It can be connected to other electrical equipment using straightforward methods, such as bolt connections, which significantly shorten installation time and reduce costs. Additionally, when expanding the electrical system—such as adding new load devices—the bus bar allows for easy expansion.
  • 【High reliability and Safety】 The 300A bus bar has undergone rigorous design and manufacturing processes, ensuring high reliability and safety. Its stable electrical performance and robust mechanical structure guarantee long-term operation, reducing the risk of power system interruptions caused by bus bar failures. Each terminal block includes a cover to protect connections from damage and corrosion.
  • 【The Function: Passive Equilibrium】 During the charging and discharging process of the battery pack, passive equilibrium helps reduce differences between individual battery cells. This ensures that each battery receives the same input and output current. Additionally, it is important to maintain equal distances from the load to each battery connected in parallel, with those distances being proportional to the resistance.
