This is a line-protection design (not a motor-protection or ground-fault variant), so it lives on the feeder or distribution side of the panel, sized for the full-load ampacity of the downstream bus. Breaking capacity climbs with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and holds 11.9 kA at both 500 V and 690 V. That curve tells the selectivity story — at 415 V the 52.5 kA SCCR gives headroom for most industrial distribution panels without cascading upstream. At 690 V the 11.9 kA figure still clears a fault in a 480 V corner-grounded delta or a 600 V class installation. Thermal derating is published per the datasheet: 125 A frame rating holds flat from 40 °C through 50 °C, then drops to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C.
Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. The 4-pole width (101.6 mm) is the standard 4-module footprint for the 3VA platform — it clips onto the mounting plate or DIN rail and occupies the same horizontal space as the 3VA1110 and 3VA1112 siblings. If the BOM calls for remote tripping or earth-leakage, you step up to the 3VA1 with the appropriate accessory slot or the 3VA2 electronic-trip family.
