the mechanism of low voltage miniature circuit breaker is very complicate, thus its assembly dimension chain and the tolerance of critical dimensions are researched.
由此,对微型断路器机构的装配尺寸链和关键尺寸公差进行了研究。
the fault mode and test method of reliability of miniature circuit breaker (mcb) were proposed.
提出了小型断路器的可靠性故障模式和试验方法。
s260 series miniature circuit breaker (mcb), which is the new generation of mcb and pushed out by abb. it's features, performances, specifications, and how to choose correctly were introduced.
because bi metal element in miniature circuit breaker is easily affected by ambient temperature change, the protective characteristic of overload will be changed with ambient temperature change.
