CBA Series AC Current Band Monitor

The CBA Series is used to detect UNDER and OVER CURRENT conditions. When the monitored current is within the normal current band, both internal relays are de-energized (Drop-out). When the current rises above the over current setting for longer than 1.0 second, the over current relay energizes (Pick-up). If the current falls below the under current setting for longer than 1.0 second, the under current relay energizes. When the monitored current returns to normal, the relays will automatically reset. The over and under current trip points are independently adjustable. An External CT may be used to extend the range of the Current Monitor.
