Circuit breakers are connected in front of the board, behind the board, insert type, drawer type, if the user has no special requirements, according to the board before supply, board before wiring is a common way of wiring.
1. Wiring mode behind the board: the biggest characteristic of the wiring behind the board is that the circuit breaker can be replaced or repaired without rewiring. It is only necessary to disconnect the front-stage power supply. Due to the special structure, the product has been configured according to the design requirements of the special installation plate and installation screws and wiring screws, need to pay special attention to is due to the large capacity circuit breaker contact reliability will directly affect the normal use of circuit breakers, so the installation must be paid attention to, strictly in accordance with the requirements of the manufacturer for installation.
2, plug-in wiring: in the installation board of the complete set of devices, first install a circuit breaker mounting block, mounting block on the 6 plugs, circuit breaker connection board has 6 sockets. The mounting pedestal is provided with connecting plate on the surface or bolt behind the mounting pedestal. The mounting pedestal is connected with power line and load line in advance. When in use, insert the circuit breaker directly into the mounting mount. If the circuit breaker is broken, just pull out the broken one and replace it with a good one. Its replacement time is shorter than before and after the board wiring, and convenient. Because insert, pull need certain manpower. Therefore, the plug - in products in China are limited to a maximum current of 400A. This saves maintenance and replacement time. During installation, the plug of the circuit breaker shall be checked for tightness and the circuit breaker shall be securely fastened to reduce contact resistance and improve reliability.
3. Drawer type wiring: the drawer of circuit breaker is rotated clockwise or counterclockwise by rocker, which is adopted in the main loop and the secondary loop
Insert type structure, omits the isolator that the fixed type must have, achieves one machine and two USES, improves the economy of use, brings great convenience to operation and maintenance at the same time, increases the security and reliability. In particular, the drawer holder of the main circuit contact tool holder, and NT type fuse breaker contact tool holder universal.
