ARM3E series moulded case circuit breakers include thermal magnetic type, electronic type and leakage type circuit breakers, they have reinforced BMC base, BMC middle cover and nylon upper cover.  2. ARM3E highlightsThe circuit breaker has overload, short circuit and undervoltage protection functions, and can protect lines and power equipment from damage.1. According to the rated ultimate short-circuit breaking capacity, the circuit breakers are classified into four types: C (economic type), L (standard type), M (medium breaking type) and H (high breaking type). 2. ARXM3E accessories are modularized, safe and reliable, with small volume, high breaking capacity, short flashover, high vibration resistance, etc.3. The circuit breaker has passed the test requirements of GB/T2423.10 and GB/T2423.18, and can withstand the influence of humid air, salt mist, oil mist and mold4. The neutral pole type of ARXM3-125~630 is A/B circuit breaker when it is of 4 poles specification, which can have a unique function of "overload alarm without tripping" to ensure the continuity of power supply and meet the requirements of Article 6.3.6 of GB50054.5. It is required to withstand mechanical vibration with frequency of 2Hz~13.2Hz, displacement of ± 1mm, frequency of 13.2Hz~100Hz and acceleration of ± 0.7g;  3. Material advantages of ARM3E productsOne of the material advantages of ARM3E products ---- heat shrinkable insulating materialsThe nylon materials such as the upper cover of ARM3E are halogen-free VO flame retardant, high and low temperature resistant, aging resistant high-quality plastics, brand: reinforced flame retardant nylon PA66.The products have longer electrical life and strength, better appearance and higher breaking capacity.Engineering plastics are resistant to high and low temperatures, ultraviolet rays, aging resistance, good insulation strength, and good dimensional stability of parts to ensure that the product does not degrade performance in complex working environments; The second material advantage of ARM3E product---- alloy contact with high silver content: the silver content can reach 95%1,High silver content, high conductivity, thermal conductivity, arc resistance, electric wear resistance,2,Preparation of dynamic and static contact material standards and reliable process guarantee, improving the electrical life of circuit breaker by 50%. The third material advantage of ARM3E product ---- mechanism:High quality high carbon steel materials, iron base ma
