AIRCircuit breaker

Universal type circuit breaker, also known as frame type circuit breaker, is a mechanical switch that can make, carry and break current under normal circuit conditions, and can also make and carry a certain time and breaking current under specified abnormal circuit conditions. Electrical appliances. Universal circuit breakers are used to distribute electrical energy and protect circuits and power equipment from overloads, under-voltages, short circuits, etc.
This type of circuit breaker generally has a steel frame, and all parts are installed in the frame. It has a large capacity, can be installed with multiple functions of tripping devices and more auxiliary contacts, has a higher segmentation capacity and thermal stability, so it is often used in places requiring high breaking capacity and selective protection.
Intelligent universal circuit breakers are suitable for AC 50Hz, rated voltages of 380V, 660V, and rated currents of 200A-6300A in the distribution network. They are mainly used to distribute electrical energy and protect lines and power equipment from overload, undervoltage, short circuit, single-phase The circuit breaker has a variety of intelligent protection functions, which can achieve selective protection, accurate action, avoid unnecessary power outages, and improve power supply reliability. Under normal conditions, it can be used for infrequent switching of lines. The circuit breaker below 1250A can be used to protect the motor from overload and short circuit in the AC 50Hz voltage 380V network. Under normal conditions, it can also be used for infrequent starting of the motor.
