Part Numbering System
1.The key feature of the end of electrical life is that the main contact insulation resistance does not meet the requirements;
2.No rule of the product installation direction , can be installed arbitrarily ;
3.When the product air-leaking or breaking fault current , please replace it immediately;
Outline dimensions
1.The fixed screw should be prepared by customers themselves, we recommend M3 screw to install the product, recommend torque is 0.8~1.3N.m;
2.If you have other special requirements for the accessories, please contact the factory or local office;
