| CBA Series AC Current Band Monitoring Relay |
| Series Description: The CBA Series AC Current Band Monitoring Relay from the ATC Diversified Electronics division of Marsh Bellofram is used to detect both under and over current conditions which could have a potentially negative effect on the continuous operation of motors, pumps or other critical industrial machinery. When the monitored current is within the normal current band, both internal relays are de-energized (drop-out function). When the current rises above the over current setting for longer than 1.0 second, the over current relay energizes (pick-up function). 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. |
