We all know that the electricity we use in our daily life is alternating current (AC), the biggest characteristic of AC is that it is unstable and changes more. That for such electricity, most of us are controlled by circuit breakers, which is now the most common is the universal circuit breaker, universal circuit breaker is mainly in the 50HZ voltage of 380V, 660V or DC voltage of 440V, etc. is widely used, he can not only protect the circuit to prevent short-circuiting, overloading, under-voltage, etc., and also protect the motor short-circuit overload and so on, then next Xiaobai give We share the knowledge about the universal circuit breaker in detail.
What are the brands of universal circuit breakers
Universal circuit breakers are suitable for AC 50Hz voltage 380V, 660V or DC 440V, current up to 3900A power distribution network, used to distribute power and protect the line and power equipment overload, undervoltage, short-circuit, etc., in the normal conditions, can be used as a line of infrequent switching. 1200V is the most common circuit breaker in the world. Under normal conditions, it can be used for infrequent switching of lines. 1250A circuit breakers can be used for overload and short-circuit protection of electric motors in the network of AC 50Hz and 380V. Under normal conditions, it can also be used for infrequent starting of motors.

The above is a small white to give you a detailed sharing of knowledge about the universal circuit breaker, I hope you can share through our content can better understand the knowledge of the universal circuit breaker. Universal circuit breaker in our life is very common, and the role is also very big, he can not only protect the circuit motor overload, exercise, undervoltage and other conditions, but also to ensure that the motor can be used normally. And now the universal circuit breaker is also more and more self-energizing.
