YCCH6 Silent AC Contactor

YCCH6 Silent AC Contactor

The YCCH6 Silent AC Contactor is an industrial-grade AC contactor designed for reliable switching of AC loads with reduced operating noise (“silent” coil design). It is suitable for frequent switching in motor control circuits, HVAC systems, lighting, and other electrical load applications where mechanical noise reduction and long service life are priorities. The contactor complies with IEC 60947-4-1 / GB 14048.4 standards, offers robust contact durability, and supports multiple coil voltage options for flexible installation.
