The 3VA1150-4EF32-0HC0: Breaking capacity varies sharply with system voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. For a 480 V panel, the 52.5 kA figure at 440 V is the closest published value — expect similar or slightly lower at 480 V.
Footprint is 130 mm high by 76.2 mm wide by 70 mm deep — standard 3-pole MCCB envelope for DIN-rail or screw-mount panel integration.
75.6 kA at 415 V, with 52.5 kA at 440 V and 11.9 kA at 690 V.
The 3VA1110-5EE32-0JA0 is a peer in the same SENTRON family, but its release and breaking ratings differ — verify the specific trip curve and fault current requirements before substituting.
