产品描述

The scope of products:
1. it is used for the driving and controlling system of mining equipment and mechanical vehicles.
2. it is used for power control and circuit insulation of industrial machinery.
3. for DC switch equipment.
4. for battery distribution and backup.
5. for the charging of hybrid electric vehicles and electric vehicles

The characteristics of the product:
1. reliable sealing makes the product used in bad and explosion-proof environment for a long time, and its coil, contact and other internal components are not oxidized.
At the same time, the product has the advantages of low energy consumption, little heating, long life, small volume, light weight and so on.
2. control high voltage and large current
3. energy saving
Some specifications of the products are used for energy saving.
4. smaller arcs are more effective and safer when the product is used
Using an inert gas seal, the product has no arc between the contacts when the product moves, and the magnetic blow out arc is used.
All is guaranteed.
5. high stability
The internal mechanism and structure are completely sealed in the inert gas and are not disturbed by external factors, and the contact resistance is stable for a long time.
6. a wide range of applications
The use includes: DC power control, battery switch control, circuit safety protection and so on.

Matters needing attention:
1. when installing the contactor, the washer should be used to prevent the screw from loosening.
2. the products with the polarity should be connected according to the marking on the end of the product. The position of the non polar products is not required.
3. do not install this product in a strong magnetic field (near a transformer or magnet) or close to a thermal radiation source.
4. this product has its own electrical life, do not use in excess of its switching capacity and life parameters.
5. ensure the use of the environment temperature in the range of -40~+85 C, high temperature is easy to accelerate the diffusion of internal inert gas, avoid storage.
Use the product in a high temperature environment.
When 6. resistance load is used, it is used in accordance with the rated parameters of the main contact. If the connection of the inductive load (L load) is L/R > 1ms, this sense should be used.
A shunt surge current protection device with a parallel load.
When 7. wiring is installed, attention should be paid to ensuring the cleanliness of the main elicited end and connection head, and tighten to avoid excessive heating at the lead end connection.
