Remarks

1. The rated electrical life is based on resistance load test. The load max inductance≤300μH; If used with inductive load, please do contact the factory first.
2. The above curve is drawn according to the test and infer data. Suggest users confirm in practical use.
3. When the product’s Dielectric withstand voltage、insulation resistance is less than the product parameters in the table, the product is defined as a life to an end.
4. Product max pick-up current is 300A to avoid contact cold welding
