Adjustable Rating Plugs for PowerPacT™ P-Frame and R-Frame and MasterPacT™ NT and NW Circuit Breakers—Selection
To provide maximum design flexibility, system protection, and field upgradeability, each MicroLogic™ trip unit is equipped with an interchangeable long-time rating plug. Each trip unit requires an adjustable rating plug to determine the long-time pickup range of the circuit breaker. These plugs are factory installed on new trip units, or can be ordered separately for field-installable upgrades.
Adjustable rating plugs are offered in eight different ranges of long-time pickup adjustments. The following chart show the ranges of adjustments. Each adjustment times the sensor rating (lr x In) of the circuit breaker sets the long-time pickup value of the circuit breaker.
