The circuit breaker is protective, can extinguish the arc, and has the ability to segment. Contactor is the use of coil to control the circuit on and off, after the contactor is energized, the normally open is closed, and the long closed is opened, so as to control. 1, the circuit breaker is mainly

Ac contactor working principle and internal structure diagramElectromagnetic system: It includes coil, static core and moving core (also known as armature).Contact system: It includes main contact and auxiliary contact. The main contact allows a large current to pass through, which plays the role of

How can we properly select low-voltage circuit breakers? Let's take a closer look at it!(1) The rated current of the circuit breaker is determined by the calculated current of the line.(2) The short-circuit setting current of the circuit breaker should avoid the normal working starting current o

Selection of AC contactors under different loadsLow voltage contactor as a device to switch off the load power supply, the selection of contactor should meet the requirements of the controlled equipment, in addition to the rated working voltage and the rated working voltage of the controlled e
