    • A fire plate for receiving a bored in lock assembly and preventing passage of fire through a lock opening bored perpendicularly through a fire door. The fire plate is particularly adapted for use with integrated lock and latch assemblies that are designed for installation through a latch opening bored from an edge of the door into the lock opening. The latch opening has a diameter less than the lock opening and the fire plate blocks the space above and below the lock assembly in the lock opening to prevent the passage of smoke and fire through the lock opening. The fire plate includes two fire stop barriers that may be formed by bending from a sheet of spring steel and which preferably snap into engagement with the lock assembly as it is inserted from the latch opening into the lock opening.
    • 用于接收锁定组件中的无孔的防火板,并防止火通过穿过防火门垂直穿过的锁定开口。 防火板特别适用于集成的锁和闩锁组件,其被设计用于通过从门的边缘钻入锁定开口的闩锁开口来安装。 闩锁开口具有小于锁定开口的直径,并且防火板阻挡锁定开口中的锁定组件上方和下方的空间,以防止烟雾通过锁定开口。 防火板包括两个防火挡板,其可以通过从弹簧钢板弯曲而形成,并且优选地在其从闩锁孔插入锁定开口时与锁定组件卡扣接合。

    • A neutral pole for a multipole circuit breaker is disclosed. The circuit breaker includes a housing, a plurality of contact arms for opening and closing an electrical circuit, and an operating mechanism for driving the contact arms. The neutral pole includes a neutral housing, a conduction path within the neutral housing having a neutral arm arranged to open and close the conduction path, a bias spring configured to exert a first bias moment on the neutral arm when the conduction path is closed, a spring support configured to support the bias spring, a rotor pivotally arranged within the neutral housing and configured to displace the neutral arm and to open the conduction path, and a drive pin configured to couple the rotor to the multipole circuit breaker. The spring support is fixedly arranged at the neutral housing. The rotor is responsive to the opening and closing action of the operating mechanism of the multipole circuit breaker.
    • 公开了一种用于多极断路器的中性极。 断路器包括壳体,用于打开和关闭电路的多个接触臂,以及用于驱动接触臂的操作机构。 中性极包括中性壳体,中性壳体内的传导路径具有布置成打开和闭合导电路径的中性臂;偏置弹簧,其构造成当导通路径闭合时在中性臂上施加第一偏置力矩; 弹簧支撑件,其构造成支撑偏置弹簧;转子,其枢转地布置在所述中性壳体内并且构造成使所述中立臂移动并打开所述传导路径;以及驱动销,所述驱动销被配置为将所述转子耦合到所述多极断路器。 弹簧支架固定地设置在中立的外壳上。 转子响应多极断路器的操作机构的打开和关闭动作。
