Main Ratings
* Above 40°C (104°F), the current rating is
reduced by 1.6A/
°C (0.88A/°F)
AC Supply Ratings
Voltage (phase-to-phase and phase-to-ground):
480V +10%
AC supply frequency: 48 to 62 Hz
Ground Leakage Current
The ground-leakage current, phase-to-phase and
phase-to-ground, when the AC supply is 400V at
50Hz is as follows:
For other AC supply voltages and currents, scale
the value of leakage current proportionally.
Discharge Resistors
A and B: 330 KΩ internally between phases, with
the star point connected by a 1M resistor to ground.
C to G: 10 MΩ internally between each phase
and ground.
Maximum Current Overload
150% of rated current for 60 seconds.
