High Quality 4P SPD 420V 20KA~40KA House Surge Protector
A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overload or short-circuit and under-voltage faults, they can automatically cut off the circuit. Its function is equivalent to a fuse switch. Combination with overheating and underheating relay, etc. Moreover, it is generally not necessary to change the components after breaking the fault current. It has been widely used. Power distribution is an extremely important link in the generation, transmission and use of electricity. The power distribution system includes transformers and various high and low voltage electrical equipment, and the low voltage circuit breaker is a widely used electrical appliance. The main contacts of the low-voltage circuit breaker are closed manually or electrically. After the main contact is closed, the free trip mechanism locks the main contact in the closed position. The coil of the overcurrent release and the thermal element of the thermal release are connected in series with the main circuit, and the coil of the undervoltage release is connected in parallel with the power supply. When the circuit is short-circuited or severely overloaded, the armature of the overcurrent release is pulled in to make the free release mechanism act, and the main contact disconnects the main circuit. When the circuit is overloaded, the thermal element of the thermal release will heat up and bend the bimetal, pushing the free release mechanism to act. When the circuit is undervoltage, the armature of the undervoltage release is released. Also actuate the free trip mechanism. The shunt release is used for remote control. During normal operation, its coil is powered off. When distance control is required, press the start button to energize the coil.Key FeaturesOrigin：CN(Origin)
