Application
Created by a DC contactor manufacturer, the fully enclosed high-voltage 12v DC contactor has the characteristics of high voltage resistance, dustproof, waterproof, and vibration resistance.
DC contactor manufacturers use high-quality insulation materials and high-strength shell designs to manufacture DC contactors that can withstand high voltages up to thousands of volts.
DC contactor manufacturers NANFENG provides good sealing performance DC contactor, effectively preventing dust, water vapor and other external environments from invading internal components.
Ordering Notice
For example: TK50D/12V
The DC contactor of main contact is one NO, rated voltage not more than DC 750V,current 500A, coi
