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

Surface treatment and processing technology of mechanism parts: QPQ heat treatment technology imported from Germany.
\n1. We selected the operating mechanism (steel) of W9-Group and another brand sample to compare the experimental results.
\n2. The operating mechanism of W9 group has a hardness of 366.1, while the hardness of the other brand is only 252.6, which cannot even reach our lowest value.\u00a0\u00a0
\n3. The mechanical life and electrical life are very important indicators in the national standard of the circuit breaker, and our circuit breaker operating mechanism needs to reach a certain strength and hardness, so that the circuit breaker will not damage the service life of the circuit breaker in the opening and closing process, while the hardness of the other brand is far lower than the national standard.<\/p>\n
