What is the power contactor
AC contactor contacts, made of silver tungsten alloy, with good conductivity and high temperature ablation.
The main contact is generally only normally open contacts, and auxiliary contacts often have two pairs of normally open and normally closed contact, small contactor is often used as an intermediate relay with the main circuit
AC contactor using the main contact to open and close the circuit, with auxiliary contacts to control the implementation of instructions.
AC contactors are widely used as power break and control circuits. (Play the role of frequent switching)
