How many connection modes of circuit breaker?

    The connection modes of circuit breakers are mainly divided into four types: front-board connection, back-board connection, insertion connection and drawer connection.

    1.Front panel wiring

    Front panel wiring is the default wiring mode of circuit breaker. If front panel wiring mode is adopted, no special explanation is needed.

    Users can install the circuit breaker before the complete set of equipment, that is, directly connect the power line and load line on the connecting board of the circuit breaker base, and fasten the connection with screw.

    2.back panel connection

    Backboard wiring means that when the circuit breaker is installed in a complete set of equipment, the connecting plate on the base of the circuit breaker is connected with the power and load wires through the bolts of the installation plate.

    Its greatest feature is that when replacing or repairing circuit breakers, it is not necessary to reconnect, but only to disconnect the front power supply.

    Because of the special structure, the special installation plate, installation screw and connection screw have been equipped according to the design requirements when the product leaves the factory.

    Special attention should be paid to the fact that the contact reliability of large capacity circuit breakers will directly affect the normal use of circuit breakers. Therefore, attention must be paid to the installation and the installation should be carried out strictly in accordance with the requirements of the manufacturer.

    3.Plug-in wiring

    Plug-in wiring refers to the installation of a set of equipment on the installation board, first installed with six sockets, and circuit breaker connection board with six sockets supporting the use. There is a connecting plate on the surface of the mounting seat or a bolt behind the mounting seat, and the mounting seat is pre-connected with power supply and load wire.

    When in use, the user can insert the circuit breaker directly into the mounting seat for use. If the circuit breaker is damaged, only need to be pulled out and replaced. The replacement time is shorter and more convenient than the wiring before and after the board.

    4.Drawer connection

    Drawer wiring is generally used for the installation of universal circuit breaker. The drawer of circuit breaker is rotated by rocker in or out of time. Insertion structure is adopted in both main and secondary circuits, eliminating the isolator necessary for fixed installation. It can achieve one machine for two purposes, improve the economy of use and increase safety and safety. Reliability also brings great convenience to operation and maintenance.
