    • Disclosed is a handle locking device including a first frame, a first hook and a second frame, wherein a second hook is provided on the first frame. The first and second hooks are rotatably installed on the first frame, and the second frame capable of fixing the first hook and the first frame. Since the handle locking device is only be installable on a circuit breaker by mating between the first hook and a first installation part of the circuit breaker and mating between the second hook and a second installation part of the circuit breaker, an operator is prevented from unintentionally setting an “OFF” position of the handle locking device in an “ON” position of the circuit breaker during installation. The first hook is rotatably installed on the first frame, so that the handle locking device can be conveniently and rapidly installed on or demounted from the circuit breaker.
    • 公开了一种手柄锁定装置,其包括第一框架,第一钩子和第二框架,其中第二钩子设置在第一框架上。 第一和第二钩可旋转地安装在第一框架上,第二框架能够固定第一钩和第一框架。 由于手柄锁定装置只能通过在第一钩和断路器的第一安装部分之间配合并且在第二钩和断路器的第二安装部之间配合来安装在断路器上,因此防止操作者无意地 在安装期间将手柄锁定装置的“OFF”位置设置在断路器的“ON”位置。 第一钩被可旋转地安装在第一框架上,使得手柄锁定装置可以方便和快速地安装在断路器上或从断路器上拆卸。
