Description:
Current level selection needs to be based on output wire specifications; and output terminals should be maintained the temperature is less than 175 °C.
Estimated product on/off life curve under resistive load:
The curve of the number of times of product on-off life expectancy under resistive load
YEV100
Remarks:

1. Suitable for resistive loads with a maximum inductance of 300uH.
2. The insulation strength between the terminals is reduced to 50 MΩ at the end of life.
3. This curve is an estimate of the inferred data and is only for reference when the customer uses it. It is recommended to confirm the experiment for different situations.
Order mark example:

YSEV50   A
Coil rated working voltage:   A=12V; B=24V; C=48V
Product serial number:YSEV50=12-900VDC, rated current 100A high voltage DC contactor

Note: The coil lead length can be customized.
Dimensions and installation dimensions:
CAONIDAYE
Precautions:

1. Use a washer to prevent the screws from loosening during installation.
The torque range of the tightening screw is as specified below. Exceeding the maximum torque can cause the product to rupture.
The force distance of the contact (M5 bolt): 3.4 -4.5N·m; the torque at the installation: 1.7-3.3 N·m.
2. The output end of this product is polar, so the connection should be operated according to the corresponding polarity.
3. Use products that have been dropped carefully.
4. Avoid installing the product in a location with strong magnetic fields (near the transformer or magnet) or near objects with thermal radiation.
5. Electrical life
This product is a mechanical contact switch. In its final failure mode, it may lose its proper shut-off function, so do not use it beyond its switching capacity and life parameters. Once the contactor loses its cutting ability, it may cause the surrounding parts to burn.
6. Internal gas diffusion life
This product is sealed with epoxy. The chamber is filled with inert gas. The diffusion life of the gas is determined by the temperature inside the contact chamber (ie ambient temperature + contact temperature rise). The working environment temperature should be -40 to +85 °C. .
7. When the resistive load is used, the rated value of the main contact in the rated value is applicable. If an inductive load (L load) is used and L/R>1ms, a surge current protection device should be connected in parallel with the inductive load.
8. Avoid miscellaneous materials and oil stains on the main lead-out; the external terminal should be in reliable contact with the main lead-out of the product, otherwise the lead-out will be severely heated.
 9. This product is recommended to use an altitude of 2500m or less. When the altitude exceeds 2500m, please contact the manufacturer.
