High Voltage DC Contactor 12Vdc-900V200A High Load Current Electric DC Circuit Control

Product Feature
High Voltage 12Vdc-900V dc Contactor Relay 200A High Load Current Electric Control China Supply

Product features:1.Controllable DC high current high voltage2.Compact structure, low working noise3.High safety4.Contact reliability is high5.No special requirement for installation6.Use diversity


Product Characteristics:



1,High current and voltage controlling This product is sealed with epoxy resin and filled with inert gas in the contact chamber. Combined with magnetic quenching, it is subjected to high current and high voltage.2,Compact structure & low noiseThe shape is small because of using an arc-free gap structure that does not allow the arc to leak.The structure in which the contacts are sealed in the inert gas compartment.Efficient and safe shut-off is ensured even if the contact gap is small.Low noise at work, as well as switching high currents.3,Excellent safety performanceThe contact is sealed in the sealed compartment,thus arc can't be released which ensuring good safety of the product.4,Excellent reliability Sealed with inert gas,the contact resistance remains stable regardless of the environment. It is also dustproof and waterproof .5,No special requirement for installation.The moving part is light,but with huge counter-force.Barely affect by gravity. So there is no special requirement for installation position.6,Multifunctional purposes Application includes:battery switch, backup equipment, DC voltage power controlling and circuit safety protection device etc.,7,Conforms with EU RoHS Instruction (2002/95/EC)
