What is an AC contactor? The contactor is an intermediate control element, which has the advantages of frequent on and off lines and large current control with a small current. Working with the thermal relay can also provide a certain overload protection for the load device. Because it relies on electromagnetic field suction to open and close work, it is more efficient and more flexible than manual switching and closing circuit. It can divide and load multiple load lines at the same time, and...
AC contactor working principle When the coil is energized, the static iron core generates an electromagnetic suction force, and the moving iron core is attracted. Since the contact system is linked with the moving iron core, the moving iron core drives three moving contact pieces to operate at the same time, and the contact is closed, thus connecting power supply. When the coil is de-energized, the suction force disappears, and the moving part of the moving iron core separates due to the...
What is the cable tie? For the purpose of the cable tie, the cable tie is also called: cable tie, cable tie, and lock tape. Ordinary cable ties (nylon) are divided into: self-locking nylon cable ties, sign ties, live buckle ties, tamper (lead) cable ties, fixed head ties, bolts (aircraft heads) Cable ties, beaded ties, fishbone ties, weathering harnesses, etc. The cable tie, as the name suggests, is a strap for strapping things. It is designed with a stop function (except for the live button...
