Tips: Composition of 3 phase AC magnetic contactor
AC magnetic contactor is mainly composed of an electromagnetic system, contact system, arc extinguishing system and other parts.
- Electromagnetic system: The electromagnetic system includes electromagnetic coil and iron core, which is an important part of the contactor, relying on it to drive the closing and opening of the contacts.
- Contact system: The contact is the executive part of the contactor, including the main contact and the auxiliary contact. The function of the main contact is to connect and break the main circuit to control a larger current, and the auxiliary contact is in the control circuit to meet the requirements of various control methods.
- Arc extinguishing system: The arc extinguishing device is used to ensure that the arc generated when the contact opens the circuit is reliably extinguished, reducing the damage of the arc to the contact.
- Other parts: Insulating shell, spring, short-circuit ring, transmission mechanism, etc.
