\nMCCB\u00a0Highlights
\n<\/h2>\n

The circuit breaker has overload, short circuit and undervoltage protection functions, and can protect lines and power equipment from damage.
\n1. According to the rated ultimate short-circuit breaking capacity, the circuit breakers are classified into four types: C (economic type), S (standard type), M (medium breaking type) and H (high breaking type).\u00a0
\n2. WLM6 accessories are modularized, safe and reliable, with small volume, high breaking capacity, short flashover, high vibration resistance, etc.
\n3. The circuit breaker has passed the test requirements of IEC60947-2 and can withstand the influence of humid air, salt mist, oil mist and mold.
\n4. It is required to withstand mechanical vibration with frequency of 2Hz~13.2Hz, displacement of \u00b1 1mm, frequency of 13.2Hz~100Hz and acceleration of \u00b1 0.7g;<\/p>\n
