How to install circuit breakers?

Everyone should know about circuit breakers. It plays a key role in home security. There are many varieties of circuit breakers. Different installation locations and installation functions involve the selection of circuit breakers. So, how to install the circuit breaker? How should the circuit breaker be connected?

Wiring method behind the board: The biggest advantage of wiring behind the board is that the circuit breaker can be replaced or maintained, without re-wiring, just cut off the front switch power supply. Due to the unique structure, the product has been equipped with a special type of mounting plate, mounting screws and terminal screws according to the design regulations. It should be noted that the stability of the touch of the circuit breaker in the large space will also endanger the conventional application of the circuit breaker, so we must pay attention to the installation and strictly follow the manufacturer’s standards for installation.

Plug-in wiring: On the mounting plate of the mechanical equipment, first install the mounting seat of the circuit breaker, there are 6 power plugs on the mounting seat, and there are 6 power sockets on the connecting plate of the circuit breaker. There is a connecting plate on the surface of the installed seat or the anchor bolts after the seat is installed, and the installed seat is connected to the power plug and the load line in advance. When applying, install the circuit breaker on the seat immediately. If the breaker is broken, just pull out the bad one and replace it with a good one. The replacement time is shorter and more convenient than the wiring before and after the board. Because the power plug, pulling it out requires a certain amount of human resources. Therefore, the frame current of Chinese plug-in products is limited to more than 400A. This reduces protection and replacement time. When installing a plug-in circuit breaker, check whether the power plug of the circuit breaker is locked tightly, and securely tighten the circuit breaker to reduce loop resistance and improve stability.

Drawer cabinet wiring: The access drawer cabinet of the circuit breaker is rotated clockwise or counterclockwise by the joystick for the main circuit and the secondary circuit.

The plug-in structure eliminates the isolator necessary for the mobile type, completes one machine for two purposes, improves the rationality of application, brings a great degree of convenience for use and protection, and improves safety and stability. In particular, the main control circuit contact holder of the drawer cabinet can be used together with the NT fuse circuit breaker contact holder.
