How much do you know about the wiring of miniature circuit breakers?

I. Front panel wiring

Board front wiring is the default wiring method of the circuit breaker, if the board front wiring method is used, no special instructions are required.

Users can connect the power and load lines directly on the connection board of the circuit breaker base before the circuit breaker is installed in the complete set of equipment, and the wiring is fastened with screws.

II. Behind the board wiring

Behind the board wiring means that when the circuit breaker is installed in the complete set of equipment, the connection plate on the base of the circuit breaker is connected to the power and load wires through the bolts of the mounting plate.

The most important feature is that when replacing or repairing the circuit breaker, it is not necessary to re-wire the circuit breaker, but only to disconnect the front power supply.

Due to the special structure, the product is shipped with a special mounting plate and mounting screws and wiring screws according to the design requirements.

Special attention should be paid to the reliability of the high-capacity circuit breaker contact will directly affect the normal use of the circuit breaker, so the installation must be paid attention to, strictly in accordance with the manufacturer's requirements for installation.

III. Plug-in wiring

Plug-in wiring refers to the installation of a set of equipment on the mounting plate, first installed with six sockets mount, and the circuit breaker connection plate on the six sockets supporting the use. There is a connection plate on the face of the mounting block or a bolt behind the mounting block, which is pre-wired with power and load lines.

When in use, the user can plug the circuit breaker directly into the mount for use. If the circuit breaker is damaged, just pull out and replace it. Its replacement time is shorter and more convenient than the wiring in front of the board or behind the board.

IV. Drawer type wiring

Drawer wiring is generally used for universal circuit breaker installation, the breaker in and out of the drawer by the rocker clockwise or counterclockwise rotation to complete the main circuit and secondary circuit are inserted into the structure, omitting the fixed installation of the necessary isolator, can do a machine two, improve the use of economic, in increasing safety and reliability at the same time, also brings great convenience to the operation and maintenance.
