What is the wiring mode of the circuit breaker?
The wiring mode of the circuit breaker is mainly divided into four wiring modes: front wiring, back wiring, plug-in wiring and drawer wiring.
The wiring in front of the board is the default wiring mode of the circuit breaker. If the wiring in front of the board is adopted, no special instructions are required.
Before the circuit breaker is installed in the complete set of equipment, the user can directly connect the power line and load line on the connecting board of the circuit breaker base, and fasten the wiring with screws.
Wiring behind the board
The wiring behind the board refers to that when the circuit breaker is installed in a complete set of equipment, the connecting board on the base of the circuit breaker is connected with the power line and load line through the bolts of the mounting board.
Its biggest feature is that it can replace or repair the circuit breaker without rewiring, just disconnect the front power supply.
Due to the special structure, the product has been equipped with special mounting plate, mounting screws and wiring screws according to the design requirements.
Special attention shall be paid to the fact that the contact reliability of large capacity circuit breaker will directly affect the normal use of circuit breaker, so attention shall be paid to the installation and the installation shall be carried out in strict accordance with the requirements of the manufacturer.
Plug in wiring
Plug in wiring refers to the installation of a six socket mounting base on the mounting plate of a complete set of equipment, which is used together with the six sockets on the connecting plate of the circuit breaker. There is a connecting plate on the surface of the mounting base or a bolt behind the mounting base. The mounting base is connected with the power supply and load line in advance.
When in use, the user can directly insert the circuit breaker into the mounting base for use. If the circuit breaker is damaged, just pull out and replace it. The replacement time is shorter than the wiring before and after the board, and it is convenient.
Drawer type wiring
Drawer type wiring is generally used for the installation of universal circuit breaker. The in and out drawers of the circuit breaker are completed by rotating the rocker clockwise or anticlockwise. The plug-in structure is adopted in the main circuit and the secondary circuit, omitting the isolators necessary for the fixed installation, which can be used for one machine and two times, improve the economy of use, increase the safety and reliability, and bring the poles to the operation and maintenance Great convenience.
