The interrupting ratings are the headline: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. The basic switch assembly is order code 3VA20106HL320AA0.
Sizing and selectivity notes
The adjustable thermal-magnetic trip unit covers a range from 150 A minimum to 1 200 A maximum. That 150 A minimum is the lowest continuous-current setting; the 1 200 A maximum is the highest short-circuit pickup. For a 100 A continuous load, the trip unit is set at the low end of its range, which gives good coordination with downstream 100 A branch breakers. Maximum power loss is 13.5 W — relevant for panel thermal calculations if multiple breakers are ganged in a small enclosure.
