DC Contactors: High Voltage, Lightweight and Environmentally Sealed
Engineered for aerospace and defense applications, our DC contactors are rated to make, break and carry 500 amps, with overload ratings up to 2,000 amps. We offer DC contactors with either electronic or mechanical economizers, or we can provide basic contactors to which you may apply your own economizer circuits..
HARTMAN DC Contactors
For the most severe environmental conditions HARTMAN DC contactors are lightweight and environmentally (gasket) sealed, with hermetically-sealed enclosures available for most severe environmental conditions or altitudes above 50,000 feet. Multiple main contact configurations and auxiliary contact configurations are available. AC and DC contactors are designed to meet the applicable requirements of MIL-PRF-6106 and/or specific customer specifications.
