CMB Series Diversified Electronics atcdiversified.com 800.727.5646 238 Current Monitors // CMB Series The CMB Series relay is used to detect the presence of AC current. When the monitored current exceeds the trip point for longer than 30 milliseconds, the internal relay energizes. When the monitored current drops below the trip point for longer than 0.5 seconds, the internal relay deenergizes. The Delay-on-Release is incorporated to prevent nuisance tripping caused by momentary dips in the load line. An External CT may be used to extend the range of the Current Monitor.
