1For remote receiving and analyzing circuits and frequent starting, controlling AC motors. 2The contactor can also be assembled into a building block auxiliary contact set, an air delay head, a mechanical interlocking component, etc. to form a time delay contactor, a reversible contactor, and a star triangular starter. 3It can also be directly connected to the thermal relay to form an electromagnetic starter. 4The contactor is sensitive and has a greater carrying capacity. 5Stable connection contact is of strong conductivity.
