Tips: Different types of AC contactors
- AC magnetic contactor: The AC magnetic contactor is mainly composed of a contact system, an electromagnetic operating system, a bracket, an auxiliary contact and a shell. Because the coil of an AC electromagnetic contactor is generally powered by an AC power supply, after the contactor is energized, there will usually be a high-decibel noise, which is also a characteristic of electromagnetic contactors.
- AC vacuum contactor: The vacuum contactor is a contactor whose contact system adopts a vacuum degaussing chamber.
- Semiconductor contactor: The semiconductor contactor is a contactor that completes current operation by changing the conduction state and the open circuit state of the circuit loop.
- Permanent magnetic contactor: Permanent magnetic AC contactor is a kind of micro-power contactor formed by using the principle of magnetic poles to repel and attract each other, and replace the traditional electromagnet drive mechanism with a permanent magnet drive mechanism.
AC magnetic contactor relay with 24V/110V/220V coil, rated current up to 225 amps, is mainly used for breaking circuit and frequently starting and controlling 3 phase AC electrical motors, different contact form are optional.
