摘要： A circuit breaker superior in heat resistance, arc resistance and over-travel characteristic, and suitable for recycling or reuse is provided.
The circuit breaker includes an open/close mechanism (7, 28, 29, 31, 32) for opening and closing a moving contact (5, 25) through a retention holder (6, 26) turnably holding the moving contact (5, 25), and a base (2, 21) for turnably holding the retention holder (6, 26) and holding a stationary side contact (10, 23). Detection of any over-current causes the moving contact (5, 25) to turn, and an arc-extinguishing device (9, 34) extinguishes arc generated between the contacts. Further the base (2, 21) of the circuit breaker is formed of an insulating molded article, which is mainly composed of a crystalline thermoplastic resin and is irradiated with electron beams after molding.摘要翻译： 提供了耐热性，电弧电阻和超行程特性优异并且适于再循环或再利用的断路器。 断路器包括用于通过保持保持器（6,26）打开和关闭移动触点（5,25）的开/关机构（7,28,29,31,32），该保持保持器可转动地保持移动触点 （5,25）和用于可转动地保持保持保持器（6,26）并保持固定侧触点（10,23）的基座（2,21）。 任何过电流的检测都会导致移动触点（5,25）转动，并且灭弧装置（9,34）熄灭触点之间产生的电弧。 此外，断路器的基座（2,21）由绝缘模制品形成，绝缘模制品主要由结晶热塑性树脂构成，并在成型后用电子束照射。

摘要： An improved miniature circuit breaker (1, 2) is adapted to improved automatic assembly of all components thereof. Key components of the breaker are individually and collectively designed to be susceptible to total Z-axis assembly. In particular, the trip mechanism (6) including the trip lever (31), and the associated activation means (75), tension means (43) and reset means (35) are defined by elements designed to interact in a Z-axis assemblable fashion. The trip mechanism components (6) are also designed for improved trip action and enhanced breaker performance in repeated CLOSED, and TRIP operations.

摘要： Ein Niederspannungs-Leistungsschatter (1) besitzt ein Gehause (2) aus Isolierstoff, das entlang einer Teilfuge (8) in ein Oberteil (3) und ein Unterteil (4) geteilt ist (Fig. 1).
Das Oberteil übergreift mit seinen Außenwänden die Außenwände (23) des Unterteiles (20). Auf diese Weise vermag das Oberteil Spreizkräfte aufzunehmen, die infolge der Druckbeanspruchung bei den Schattvorgängen auf die Außenwände (23) des Unterteiles (20) ausgeübt werden. Die Erfindung eignet sich insbesondere für Isolierstoffgehäuse mit ungleicher Teilungshöhe zwischen dem Unterteil und dem Oberteil, weil die auf eine Außenwand wirkende Umbruchkraft mit steigender Höhe der Außenwand zunimmt (Fig. 3).摘要翻译： 低压电力断路器（1）具有沿着接头（8）分成上部（3）和下部（4）（图1）的绝缘体壳体（2）。 上部的外壁与下部（20）的外壁（23）重叠。 以这种方式，上部能够吸收由于在下部（20）的外壁（23）处的切换过程期间的压力应力而施加的膨胀力。 本发明特别适合于具有不相等的下部和上部之间的分隔比的绝缘壳体，因为作用在外壁上的断裂力随着外壁的高度增加而增加（图3）。

摘要： A highly flame-retardant organic and inorganic complex composition without corroding metal parts, and a compact switch with excellent insulation properties after opening and closing electrodes, are provided. An organic and inorganic complex composition wherein the resin content is at 15 to 70 wt % and the content of one or more inorganic compounds capable of dehydration at 150 DEG C or more is at 80 to 30 wt %. When the composition is exposed to combustion, inorganic compounds being capable of dehydration at 150 DEG C or more and being contained in the organic and inorganic complex composition generate steam, which then suppresses combustion. Simultaneously, endothermic reaction during steam generation deprives combustion heat. A switch having a molded article of which the entirety or a part is composed of an organic and inorganic complex composition is provided, wherein the base inside 2a of the base of a box is composed of for example an organic and inorganic complex composition with the resin content at 15 to 70 wt % and the content of one or more inorganic compounds capable of dehydration at 150 DEG C or more at 80 to 30 wt %.
