摘要： Ein Niederspannungs-Leistungsschalter (1) besitzt ein Gehäuse (2) aus Isolierstoff. Das Gehäuse (2) ist entlang einer Teilfuge (8) in ein Oberteil (3) und ein Unterteil (4) geteilt. im Inneren ist das Gehäuse (2) zur Aufnahme der benachbarten Polbahnen des mehrpoligen Leistungsschalters durch Trennwände (52, 53) unterteilt. Die Trennwände des Oberteiles (3) und des Unterteiles (4) überlappen einander auf ihrer ganzen Länge, während sich die Außenwände (50, 51) beider Gehäuseteile (3, 4) einander im wesentlichen in ihrer ganzen Länge überlappen, d. h., es sind nur kurze Unterbrechungen der Überlappung vorhanden.
Durch die Überlappungen der Außenwände und der Trennwände wird erreicht, daß die elektrischen Kriechwege innerhalb des Isolierstoffgehäuses und von einem Isolierstoffgehäuse zu einem benachbarten Isolierstoffgehäuse verlängert werden und daß der Durchtritt von Schaltgasen in benachbarte Räume eines Schalters und zwischen benachbarten Schaltern verhindert wird (Fig. 4).摘要翻译： 甲低压断路器（1）具有绝缘材料制成的壳体（2）。 所述壳体（2）沿一分型线（8）分成上部分（3）和下部部分（4）。 所述壳体（2），用于通过隔壁接收多极断路器的相邻极路径内（52，53）被分割。 所述上部（3）和下部的分隔壁（4）彼此重叠在它们的整个长度，而两个壳体部分的外壁（50，51）（3,4）彼此重叠基本上沿其整个长度，即，它只有 重叠的短时中断存在。 由于外壁和分隔壁的重叠是这样实现的漏电路径被该绝缘外壳内，并且由绝缘材料到相邻的绝缘材料制成，并且使得防止在开关的相邻房间和相邻的开关之间切换气体的流路延长。

摘要： A circuit breaker includes a plurality of fixable bars configured to form fixable contacts, a plurality of movable bars configured to be rotated through a switch to be connected to or disconnected with the plurality of the fixable bars and configured to form movable contacts opposing the fixable contacts, a plurality of arc chambers configured to cover contact parts of the plurality of the fixable bars and the plurality of the movable bars to remove an arc being generated on the contact parts, a bottom base configured to separately accommodate the plurality of the movable bars, the plurality of the fixable bars and the plurality of the arc chambers, each being in a rotation direction and configured to be integrally molded and a top base configured to form a pair with the bottom base to separately seal the plurality of the movable bars, the plurality of the fixable bars and the plurality of the arc chambers and to be integrally molded. The circuit breaker may prevent molten material inflow in a circuit breaker through a separate seal and insulation of components, each associated with a phase when a short circuit failure occurs, may prevent insulating performance decrease through the molten material inflow, may shorten an arc extinguishing time by an internal pressure increase through separately sealing components, each associated with a phase when a short circuit failure occurs thereby the circuit breaker may easily ensure short circuit performance, may implement a separate sealing structure of the components through a vertical integration of a bottom base and a top base, may have a simple structure and may increase assembly productivity.

摘要： A circuit breaker having excellent heat resistance, arc resistance and over travel characteristics between contact points and suitable to recycle or reuse. The circuit breaker comprises mechanisms (7, 28, 29, 31, 32) for opening/closing holders (6, 26) holding movable contacts (5, 25) rotatably, and bases (2, 21) for holding the holders (6, 26) rotatably and also holding fixed side contacts (10, 23). When an overcurrent is detected, the movable contacts (5, 25) are rotated and an arc generated between contacts points is extinguished by arc-extinguishers (9, 34). The bases (2, 21) are insulating moldings principally comprising crystalline thermoplastic resin irradiated with an electron beam after molding.

摘要： The invention relates to a housing for electrical apparatus, especially for differential current detectors that can be coupled to automatic switches, comprising a base (1) and a lid (2) defining the location of the corresponding mechanism. An L-shaped piece (5) is coupled to the said array, said piece being fitted in such a way as to allow for a limited insertion and removal movement in a hole (6) on one side of the base (1). Said piece (5) defines channels (7) that are alternately defined by the inner and outer side of said piece. The external connecting wires can be located in said channels in relation to the corresponding application disconector.

摘要： The present invention has an object to provide a circuit breaker and an assembling method thereof, in which constituent units are inserted into a case (100) sequentially in one and same direction so as to improve the efficiency in automatic assembling. In the invention, an internal mechanism of a circuit breaker is divided into blocks or units of an arc-extinguishing chamber unit (400), a switching mechanism portion unit (500), an overcurrent tripper unit (600) and a manually operating handle (300), so that the respective units are inserted and assembled into a molded case sequentially in one direction to manufacture the circuit breaker. According to the invention, it is possible to provide a circuit breaker and an assembling method thereof in which the efficiency in automatic assembling can be improved.
