Product details

Motor power at 60 °C – the real rating for hot panels

The 3RT6028-1AF00: At 690 V it still delivers 47.5 kW at 60 °C, so it handles 690 V line-ups without stepping up a frame size.

Termination and wiring – screw terminals, dual conductors

Both main and auxiliary/control circuits use screw-type terminals.
