AC Contactors

AC Contactors: Small, lightweight, efficient

An AC contactor is an electrical switching device that can switch an electrical circuit on and off. Our AC contactors are available in multiple contact configurations, current/voltage ratings, auxiliary contact configurations, and mounting styles. Our AC contactor is available in voltage ranges from 12VAC or 12VDC to 690VAC or 440VDC. Economizer circuits are employed to reduce the amount of power used by the contactor coil during operation. Our portfolio of AC contactors includes products from our HARTMAN and KILOVAC brands.

AC Contactors are used mostly in applications where high current carrying capacity is required. Compact and mounted easily, these feature multiple contacts. AC contactors have shading coils that delay demagnetization of the magnetic core to avoid chattering. Our AC contactors are available in multiple contact configurations, current/voltage ratings, auxiliary contact configurations, and mounting styles. Our depth of technical experience and range of products provides our customers with solutions to help them address demanding performance requirements for harsh environments. Our portfolio includes lightweight, small, and efficient AC contactors for aerospace commercial and military electrical power systems.
