ATC CMB-120-AFA-1 AC Current Monitor Relay with Go/No-Go Function - Industrial Electrical Protection for Motors, Pumps & HVAC Systems

Product Description

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 de-energizes. 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.
