ARXM3
ARXM3 Series thermal magnetic type breaker 400V/690V 320A 400A 630A 800 amp 3/4 Poles
MCCB Highlights
ARXM3 thermal magnetic type with 3p and 4p - thermosetting insulating materials
1、The unique formula material is adopted, which has high strength, good arc resistance, strong insulation, high temperature resistance and good flame retardancy
2、 high sensitivity temperature sensor of fixed type mccb
High quality bimetallic element materials are used, and there is no need to reduce the capacity (current)from -5℃ to 55℃
3、 spring materials with longer temperature resistance and fatigue resistance (50% longer than ordinary springs)
