mc1 series

ac contactor
mc1 series ac contactors are mainly used in circuits with ac 50/60hz, rated current 9~2600a, rated voltage 1000v and below, and used for long-distance connection, breaking circuits and frequent starting control of ac motors. this series also has optional switching capacitor contactor, and can be used in combination with thermal relay, which can be widely used in civil buildings, public buildings, industrial and other industries.

special design and flexible installation


● specially designed counterforce spring structure makes the counterforce characteristics more ideal with more reliable and flexible actions
● neither vertical nor horizontal installation affects performance


high-quality materials with excellent service life


● new electromagnets are used to effectively reduce the temperature rise and noise of the product
● the max. electrical life can reach 1 million times under ac-3 category of use


various accessories for easy expansion


● a variety of optional auxiliary contacts, allowing to attach a variety of time-delayed suction, time-delayed release and auxiliary contact combinations to meet the diversified needs of customers
● special accessories can be attached to mc1 to form a switching capacitor contactor, which is suitable for reactive power compensation devices, such as centralized compensation, dynamic local compensation boxes and dry-type transformer cabinets and other equipment; it can be plugged in with mr1 series of thermal relays, which can save space for installation and eliminate wiring work.
