A low voltage circuit breaker is a switching device that can not only turn normal load current and overload current on and off, but also can turn short circuit current on and off. In addition to the control function in the circuit, the low voltage circuit breaker also has a certain protective function.
What is the protective function of the low voltage circuit breaker?
What is the plug wiring for low voltage circuit breakers?
What is the key structure of the low voltage circuit breaker?
Protection functions of low voltage circuit breakers: short circuit protection, overload protection and undervoltage protection.
low voltage circuit breakers were formerly referred to as automatic switches or air switches. In addition to full load shutdown capability, it also has functions such as short circuit protection, overload protection and undervoltage protection, and has good arc extinguishing ability. It is often used as a main switch or secondary circuit switch in the distribution box. low voltage circuit breakers should not be operated frequently and are suitable as control units in lighting distribution boxes or other rare operations.
On the mounting plate of the complete set, first install a circuit breaker mounting seat, on the mounting seat there are 6 connectors, and on the connecting plate of the circuit breaker there are 6 sockets. There is a connecting plate on the surface of the mounting seat or bolt behind the mounting seat, and the power line and load line are pre-connected to the mounting seat. Insert the circuit breaker directly into the bracket for use. If the low voltage circuit breaker is defective, just pull out the bad one and replace it with a good one. Its replacement time is shorter and more convenient than the wiring before and after the board. Because plugging in and out requires a certain amount of manpower. This saves maintenance and replacement time. When installing a pluggable circuit breaker, check that the circuit breaker plug is firmly depressed and securely fasten the circuit breaker to reduce contact resistance and improve reliability.
1. Energy-releasing electromagnet
When the user presses the button after the electromagnet coil is excited, the electromagnet is closed to release the energy storage spring, and the circuit breaker is closed.
2. Turn the handle
The operator rotates the handle outside the door clockwise or counterclockwise to ensure the circuit breaker closes or opens. At the same time, turning the handle can ensure that the cabinet door cannot be opened when the circuit breaker is closed; only when the handle is opened or buckled, the door of the control cabinet can be opened. In an emergency, when the circuit breaker is "on" and the door needs to be opened, the red release button can be pressed on the side of the rotary handle base.
