| II, Product Characteristics |
1,Controlled high current and high voltage
Sealed with the epoxy resins, filled with inactive gases inside of contactor room,combining the magnetic quenchingfor making the products bear the high current and voltage.
2,Structure is compact, the operation noise is low
Adopt the AC arc gapless structure to make the outside shape getting smaller.
Adopt the method of sealing the contactor inside of the inactive gas cabinet for ensuring the safety breaking even if the contactor gap is small.
The operation noise is low even switching the high current.
3,Good safety performance
Sealing the contactor inside of the sealed cabinet, the AC arc cannot release for ensuring the products have good safety performance.
4,Good Reliability of Contactor
Sealing the contactor unit inside of the inactive gas, the connecting resistance keeps steady whatever the environment is. And realize the dirt and water proof at the same time.
5,No Special Requirement on Installation Way
The moving part is light,but with huge counter-force,the products affect lightly by heavy force. There is no special requirement for installation position.
6,Diversity Multy-purpose
Standard purpose includes:battery switch and backup equipment, DCvoltage power controlling and circuit safety protection device etc.,
7,Conforms with EU RoHS Instruction (2002/95/EC)
