摘要:
A replaceable circuit breaker module (102) has a housing (125) for supporting and enclosing elements of the module, a circuit breaker (103) mounted in the housing in a manner that an action of installing the module connects the breaker to bridge an incoming and an outgoing conductor, and monitoring circuitry (128) for monitoring characteristics of the circuit breaker, the monitoring circuitry mounted in the housing (125) and having a first connector element (132) for engaging a mating connector element in the action of installing the module. The module is characterized in that action of withdrawing the circuit breaker module also withdraws the monitoring circuitry. Sensors in the monitoring circuitry may include sensors for monitoring one or more of breaker presence, on/off state of the breaker, and voltage provided to the breaker.

The invention relates to switchgear for an extensible circuit breaker. At least one rear terminal board (14) is provided per phase, in which the fixed connections (18) to the conductor rails (12) and the plug connections (20) for the circuit breaker are fixed. Only horizontal guide rails (4) are provided for carrying and moving the circuit breaker.

The present disclosure relates to a fuse case and a case cover of a vacuum contactor including a truck (10), a main circuit unit (12), and a front cover (15) covering a front side of the main circuit unit. The fuse case and the case cover comprises a fuse (20) connected to an upper terminal of the main circuit unit and blowing, when a fault current is generated in a circuit, to break the circuit. The fuse case and the case cover comprises further a fuse case (30) opened in an upper side, accommodating the fuse (20), and having an insertion coupling part formed on a side surface thereof. A case cover (40) is coupled to an upper side of the fuse case (30), coupled to the insertion coupling part in an insertion-coupling manner, and covering a rear end portion of the fuse, wherein the case cover (40) includes an upper surface portion and side surface portions, and the side surface portions include a first side surface portion and a second side surface portion.

Disclosed is a wheeled circuit interrupter (1) provided with a blower-attenuator for cooling and deionizing a switching gas coming from an arc quenching chamber (3). The blower-attenuator (5) consists of two bodies (6, 7) telescopically fitting into each other, one (6) of which is stationary and the other has a tight surface (10) bearing against an outlet surface (4) of the arc quenching chamber (3). Owing to the two-piece design of the blower-attenuator, the tightness between said blower-attenuator and the arc quenching chambers (3) is improved by the gas pressure.

Der Erfindung liegt die Aufgabe zugrunde, eine sichere Nebenstromkreisverbindung und eine Hilfsschalterbefestigung für Einschubschalter mit verfahrbarem Hauptkontaktträger zu schaffen, welche die Einbauhöhe der Einschübe nicht beeinflußt. Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß die Nebenstromkreisverbindung aus einer an der Seitenwand (3) des Einschubträgers angeordneten, absenk- und anhebbaren Buchsenleiste (1), einer damit korrespondierenden starr am Einschubgerät (4) befestigten Steckerleiste (2) und einem Hebelmechanismus (5, 6, 11, 12) zum Absenken, Heben oder Verharren der Buchsenleiste (1) in Abhängigkeit von Betriebsstellungen AUS-TEST-EIN des Einschubgerätes (4) besteht und daß die Hilfsschalter in einem am Einschubträger befestigten Gehäuse aufgenommen sind und über einen Schieber gesteuert sind, der an dem verfahrbaren Hauptkontaktträger angelenkt ist.
