High Voltage Relay Designs

From GIGAVAC
 

 
Below is a discussion of typical high voltage relay designs used by GIGAVAC for high voltage switching applications. Click physics of vacuum and gas filled relays to learn more about high voltage relays. GIGAVAC's HV relays are sealed, providing rugged, small, and efficient high voltage designs for most demanding applications.
Products & Services
Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other. Search by Specification | Learn more about Electromechanical Relays
Motor starters and contactors are motor-starting devices. They combine a contactor with overload protection and are designed for starting AC or DC motors. Search by Specification | Learn more about Motor Starters and Contactors
Electrical contactors are electrical devices used to switch high power in power circuits. Unlike relays, contactors are normally directly connected to the load (current carrying) circuit. Learn more about Electrical Contactors
Aerospace contactors are high-performance, high-capacity circuit controls designed for aerospace applications. Search by Specification | Learn more about Aerospace Contactors
Reed relays are electrically-operated switching devices that consist of two thin, magnetic strips (reeds) encapsulated in a glass envelope. They are used to switch industrial components such as solenoids, contactors and starter motors. Search by Specification | Learn more about Reed Relays
