Abstract
An electro-mechanical circuit breaker device incorporating a fuse cartridge, wherein two contact bars are normally connected by a series of mobile contacts held against their lower edge by springs, two in number for each. An insulating plate, suitably guided at its edges in the insulating envelope of the apparatus, receives the downward displacement that a coil applies by the Thomson effect to an aluminum disc, and it lowers the contacts against spring and latches them in open position by engagement of a bolt in a notch. The lower edge of the plate is provided with teeth to receive the successive contacts and retain them transversely, while each of the mobile contacts is notched to ensure lengthwise retention.
