Basic classification of AC contactors
The main contact function is to connect and break the main circuit, control the larger current, and auxiliary contact is in the control loop to meet the requirements of various control methods.
contact system: contact is the implementation of contactor, including the main contact and auxiliary contacts.
electromagnetic system: electromagnetic system, including electromagnetic coil and core, is an important part of the contactor, relying on it to drive the closure and opening of the contact.
The contactor is mainly composed of electromagnetic system, contact system, arc extinguishing system and other parts.
