1. Wiring after board. The advantage of the rear wiring of the board is that when the DC circuit breaker is maintained, it is only necessary to disconnect the power supply of the front stage without rewiring. These structures are special and are equipped with special mounting plates and screws. They must be installed in strict accordance with the manufacturer's requirements to avoid affecting the normal use of the circuit breaker.
2, plug-in wiring. The advantage of plug-in wiring is that when the circuit breaker needs to be replaced, just remove the old circuit breaker and replace it with a new one. It is faster than the board front and rear panel wiring, and it is more convenient. When installing by this method, ensure that the plug is securely fastened, thus reducing the contact resistance to improve safety and reliability.
3. Drawer wiring. The entry and exit drawers of products such as DC circuit breakers are realized by clockwise or counterclockwise rotation of the rocker, and the plug-in structure is adopted on the main circuit and the second circuit. This can achieve dual use of one machine, which not only saves the use cost, but also has great advantages in the convenience of operation and update maintenance.
