Breaking capacity hits 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V, so it handles high-fault industrial feeds without cascading upstream.
Three-pole footprint: 138 mm wide, 248 mm tall, 110 mm deep. Undervoltage release and phase failure detection are built in — no add-on modules needed for those protective functions. Two HP auxiliary switches come fitted for status feedback to the PLC or alarm panel.
