Miniature electric circuit breaker with multiple contacts

摘要

The invention relates to a miniature electric circuit breaker with magnetothermal trip. It includes a fixed main contact 72 arranged on a conductive part 76 supported by the fixed core 50 of the electromagnetic trip 44 and connected electrically with one of the ends of the coil 46. The arc contact 74 is carried by an elastic blade 78 equipped with an arc-guidance electrode 80 arranged between the part 76 and the extinction chamber 40. Application: protection of low-voltage networks. <IMAGE>
