200% for 3 sec.
Medium Duty: MD mode: Designed for medium duty load applications; Overload capability: 150% for
1 min.
Low Duty: LD mode: Designed for low duty load applications; Overload capability: 120% for 1 min.
SOURCE: Number of input phases (three-phase: 3PH), input voltage, input frequency, input current
OUTPUT: Number of output phases, rated output voltage, output frequency range, rated output
capacity, rated output current, and overload capability
SCCR: Short-circuit capacity
