Contact relays are used to connect control circuits and use arc extinguishers and other relays similar to contactors. The working principle of contactor relay and electromagnetic relay is the same. The contactor is connected to the electrical equipment, and the current has a large arc extinguishing device. The contact relay is used to connect the control circuit, but the contact adopts the arc extinguishing cover and other similar contactor technology, so it is called the contactor relay.
1.Epoxy encapsulation; filled the contactor with inert gas; combined with magnetic blow off; can carry large current and high voltage.
2.Due to the use of no arc clearance structure to avoid arc leakage, the shape can be very small.
3.Since we adopt the structure in which the contacts are sealed in the inert gas chamber, even if the contact clearance is very small, it is possible to ensure efficient and safe cutting.
4.Working noise is low, it is the same if switching to large current.
5.As the contact sealed in the seal cabin and the arc can not be leaked, high security of the product can be assured.
6.The contact unit is sealed in an inert gas so that the contact resistance remains stable regardless of the environment, and also can meet the dust and water resistance requirements of the contact part.
7.Weight of movable part is light; anti-force is large and the product is affected by gravity in a very small extent. There are two kinds of installation, side and bottom installation; no special requirements for the installation location.
1. With surge suppressor, no overvoltage absorption device is needed for use, which has reached EMC requirements;
2. Reliable operation with wide voltage, the working voltage of the coil can work reliably in the range of 70% ~ 130% Us;
3. The coil power consumption is 10-15 times lower than traditional products, and the coil is not easy to burn out;
4. Contacts are not easy to stick and solder;
5. No noise in the iron core;
6. Allow working environment temperature -25 ℃ ~ + 70 ℃;
7. The wide-voltage working energy-saving module is a capacitive load, and the power factor of 0.09 (leading) has reactive power compensation to the power grid.
