Wear Indicator for a Circuit Interrupter Exhaust Control Device
摘要：
An exhaust control device includes a wear indicator disposed within a housing of the exhaust control device. The wear indicator is arranged to be exposed to a flow of exhaust gas through the exhaust control device. The wear indicator has a first observable state indicative of remaining useful life of the exhaust control device. The wear indicator is responsive to a flow of exhaust gas through the exhaust control device to assume a second observable state indicative of the exhaust control device having reached the end of its useful life.
摘要（中）：

排气控制装置包括设置在排气控制装置的壳体内的磨损指示器。 磨损指示器布置成暴露于通过排气控制装置的废气流。 磨损指示器具有指示排气控制装置的剩余使用寿命的第一可观察状态。 磨损指示器响应于通过排气控制装置的废气流，以呈现指示排气控制装置已经达到其使用寿命结束的第二可观察状态。
