Heavy-duty (PhD/IhD) at 315 kW / 330 A covers constant-torque applications like extruders or crushers. Light-overload (PlD/IlD) matches normal-use power at 355 kW but delivers 360 A for short-duration peak demands. UL listings show 300 Hp heavy-duty and 350 Hp light-overload — confirm local code adoption if specifying for a North American panel.
Rated for ambient temperatures up to +55 °C and altitude to 4000 m — no derate needed at moderate elevations. Operating humidity spans 5–95 % RH non-condensing. Standby loss of 214 W and sound pressure at 75 dB(A) factor into cooling and panel layout.
