  Circuit breaker wiring board way before the board, the plug-in, drawer-type, the user, such as no special requirements, according to board before the delivery, pre-wiring board is a common wiring.
  (1) After the wiring board: Rear biggest feature is the replacement or repair circuit breaker, do not have to re-wiring, simply disconnect the power before the class. Because of the special structure, the factory has been configured according to specific design requirements of the mounting plate and mounting screws and terminal screws, require special attention because of the reliability of high-capacity circuit breaker contacts will directly affect the normal use of circuit breakers, so the installation must pay attention to, in strict accordance with manufacturer requirements for installation.

  (2) plug-in connection: complete installation of the device in the board, install a circuit breaker mount, install seat six plugs, circuit breakers of the connecting plate has six outlets. Installation of seat surface of a plate after the bolt or mount, mount a pre-connected to the power line and load line. When used, the circuit breaker directly inserted into the mounting pad. If the circuit breaker is broken, as long as the pull out the bad, put on a good can. It is time to replace the former than the board, after the wiring board to be short and easy. As the plug, pull some human need. Therefore, China's current plug-in products, the current limit in the shell stand up to 400A. Thus saving maintenance and replacement time. Plug-in circuit breaker should be installed in the plug is pressed check circuit breakers and circuit breakers should tighten security in order to reduce contact resistance and improve reliability.
  (3) drawer connection: circuit breaker out of the drawer by the joystick clockwise or counterclockwise, in the main circuit and the secondary circuit are used plug-in structure, omitted to be fixed by the isolator, do to a machine with two, increase the use of the economy, while to the operation and maintenance is a big convenience, increased security and reliability. In particular, the main circuit contact block drawer knife block, with NT-fused circuit breaker common touch knife block, so that the emergency state power directly into the fuse.
