he three-phase AC contactor has several wiring ports
the auxiliary contact is switched on and the normally closed contact is switched to off. According to this principle to apply, widely used, not detailed
Control coil is when the coil is energized, the AC contactor pulls in, the main circuit is connected
usually The top three input, the following three then output. Two sets of auxiliary contacts on both sides, both normally open and normally closed contacts available
three main line terminals were connected to three-phase AC A B C three phase lines
Usually three-phase AC contactor upper and lower ends have three main lines, two sets of auxiliary contact terminals and a set of control coil side,
