| 摘要 |
The invention relates to an electrical installation device, particularly a circuit-breaker, motor protecting switch, and similar, comprising a housing that is formed from shell-type housing parts, an electromagnetic trigger, a thermal trigger, a breaker mechanism with a latching point, a slide which transmits the movements of the thermal trigger and the magnetic trigger to t he breaker mechanism in order to unlatch the same, and a striker that is connected to the armature of the electromagnetic trigger and acts upon a movable contact piece of a contact point in case of a short-circuit so as to open the contact point. The shell-type housing parts, the slide, and the striker are made of plastic. At least the slide is formed from radiation- crosslinked thermoplastic to which an additive has been added as a crosslinking promoter before the radiation process.
