Interrupting capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V — these are high-end fault-clearing numbers that place this breaker in the large-service-entrance or heavy-industrial feeder class, not a downstream distribution panel. The thermal derating curve is published from 40 °C (630 A) through 70 °C (520 A), so you can size it for a warm enclosure without guessing.
This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
630 A continuous current, ETU350 electronic trip unit, 330 kA interrupting at 240 V, 242 kA at 415 V, 187 kA at 500 V, and 52.5 kA at 690 V. Thermal derating is published from 630 A at 40 °C down to 520 A at 70 °C.
The depth is 110 mm, with a width of 138 mm and height of 248 mm.
Yes, it includes a shunt trip (STL) auxiliary release. It does not include an undervoltage release, auxiliary contacts, communication module, or ground-fault monitoring.
