Product details

Breaking capacity — selectivity planning

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. The 121 kA at 240 V covers high-fault transformer secondaries.

Panel fit and accessories

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. Ships with two auxiliary switches (HQ type) and a shunt trip release (STL) whose integrated auxiliary trip order code is 3VA9688-0BL30. Front protection is IP40; no undervoltage release, no ground-fault monitoring, no communication module on this variant.

Frequently asked questions

What is the breaking capacity of 3VA1150-4EF32-0HC0 at 415 V?

75.6 kA at 415 V, with 52.5 kA at 440 V and 11.9 kA at 690 V.

What is the closest functional second-source for 3VA1150-4EF32-0HC0?

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.

Where can I buy 3VA1150-4EF32-0HC0?
