ARXM3
ARXM3 Series thermal magnetic type mccb 400V/690V 100A 125A 200A 320A 400A 630 amp 3/4 Poles
MCCB Highlights
Product structure of ARM3 thermal magnetic type circuit breaker
1、Safety, it can directly disassemble the upper cover of ARXM3 to install internal accessories
2、Accessory installation features: humanized design, making installation and replacement more convenient for on-site installation
3、The operating mechanism of AceReare Electric has a hardness of 366.1, while the hardness of the other brand is only 252.6, which cannot even reach our lowest value.
4、High quality low carbon cold rolled steel is used, and after QPQ salt bath composite treatment, the wear resistance, corrosion resistance and fatigue resistance of metal surface are greatly improved, and the strength, mechanical life and electrical life of parts are improved by more than 10%
