Product Description


63AMP 80AMP Circuit Breaker MCCB with IEC60947-2Scope of application
ARXM3 series molded case circuit breakers(hereinafter referred to as circuit breakers)are suitable for infrequent switching and motor starting inAC 50Hz(or 60Hz)circuits with rated insulation voltage of 1000V,rated working voltage of 690V or 400V,and rated working current of 630A (Inm≤630A and below).
The circuit breaker has overload,short circuit and undervoltage protection functions,and can protect lines and power equipment from damage. According to its rated ultimate short-circuit breaking capacity,the circuit breakers are classified into four levels:C type (economic),L type (standard),M type (medium breaking)and H type (high breaking). The circuit breaker has the characteristics of small volume,high breaking capacity,short arcing,antivibration,modular installation of accessories, simple use,etc.
The circuit breaker can be installed vertically (i. e. upright)or horizontally(i. e. transversely).
The circuit breaker has isolation function.
The circuit breaker shall comply with IEC60947-2 and GB/T14048.2.

Material advantages of ARM3 series circuit breaker products
1.Heat shrinkable insulating material;
2.Alloy contact with high silver content;
3.Mechanism parts:high quality high carbon steel materials;
4. The thermosetting insulating material adopts the unique formula material,which has high strength,arc resistance,strong insulation,high temperature resistance and good flame retardancy;
5. High sensitivity temperature sensing element is made of high-quality bimetallic element materials,and there is no need to reduce the capacity from-5ºCto 55ºCambient temperature;
6. Spring materials have longer temperature resistance and fatigue resistance(50%longer than ordinary springs).
