Tips: Types of Contactor Auxiliary Contacts
- The main contact, mostly normally open contacts, has a large current carrying capacity, and is mostly used to control motor startup and other controls.
- Auxiliary normally open contacts, play an auxiliary role, can be used for self-locking, signal transmission and other circuit requirements.
- Auxiliary normally closed contacts, to achieve linkage in complex circuits, sometimes used as motor interlock.
