Interrupting capacity of 330 kA at 240 V AC and 242 kA at 415/440 V AC means it safely clears very high fault currents typical on large industrial transformers or close-coupled busways; at 690 V it still interrupts 3.7 kA. Minimum operating current of 189 A and maximum of 945 A define the adjustable trip range — this breaker is sized for motor feeders in the 63 A frame but with a wide magnetic adjustment band.
Power loss is 4 W maximum at rated load.
It means the breaker is optimized for motor starter branch circuits — the trip curve and magnetic adjustment range (189 A min to 945 A max) are tailored to coordinate with contactors and overload relays.
