JD and LD-Frame Trip Adjustments Continuous Current (I,) and Long Time Delay Instantaneous Pickup All models have a Continuous Current and Long Time Delay adjustment. This single knob adjusts the Continuous Current setting of the circuit breaker and sets the Long Time Delay. This setting (I,) is a percentage of the Maximum Continuous Current rating (In) Two long time delay bands are available.
JD and LD-Frame Trip Adjustments Short Time Pickup/Short Time Delay (Optional) Ground Fault Pickup (Ig) (Optional) Circuit breakers with the letters “NT” in the catalog number have an adjustment to set both the Short Time Pickup and the Short Time Delay. This single knob sets both pickup and delay at the same time. Circuit breakers with the letter “G” included in the catalog number have integral equipment ground fault protection.
JD and LD-Frame Trip Adjustments The ground fault option has two modes of operation. The modes are set by a switch on the side of the trip unit with the settings identified as GROUND RETURN and RESIDUAL. See Figure 1 for switch location. Residual Setting (Outgoing Circuit Method) This is the standard position to which the breaker is set when shipped from the factory.
