▲1 _{The pull-in voltage, release voltage, and coil resistance of products without energy-saving circuit boards may change with the ambient temperature and usage conditions, so please pay attention to the electricity according to copper.The temperature coefficient of resistance can give the following theoretical calculation formula, and the calculated value and the actual value may be slightly different. Temperature rise: actual value = U × (1 + 0.004 × K), temperature drop: actual value=U×(1-0.004×K), where U=20°C rating, K=|current ambient temperature-20|}

Product features:

1.Controllable DC high current high voltage

2.Compact structure, low working noise

3.High safety

4.Contact reliability is high

5.No special requirement for installation

6.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 noise

The 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 performance

The 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)
