HI-SEISMIC HIGH DROPOUT INSTANTANEOUS UNIT
The high drooout instantaneous unit is tapped for operation on either of two ranges (H or L) . Selection
of the high or low range is accomplished by means of a movable lead located in the rear of the relay.

Since the high dropout unit coil is in series with the time overcurrent unit coil and the Hi-Seismic
instanta�eous unit coil, see Tables 3, 4, 5 and 6 to determine the current limiting element for both
continuous and short time ratings.
