MCCB circuit breaker WLM6 Series thermal magnetic type mccb 400V/690V 160A 3/4 Poles
Rated Current : 160A Number Of Poles : 3P / 4P Rated Working Voltage : 400V/690V
MCCB Highlights
The nylon materials such as the upper cover of ARXM3 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.
