Adjustment: lock shaft adjusted; tracks the operating-voltage setting (one phase below 83% or all three below 90%). Trip delay: phase loss / reversal 2 s; undervoltage 2 s. Restart: 1 s. Reset: automatic upon correction of the fault.
Output: 2C DPDT, 3 A general purpose at 120 / 240 / 600 V AC; 480 VA at 600 V AC. Mounting: surface mount (#8 screws), screw terminals. Indicator: LED, glows when all conditions are normal.
