Its headline breaking capacity is 220 kA at 240 V, stepping down to 154 kA at 415 V and 75.6 kA at 440 V — so it handles high-fault scenarios like transformer secondaries or large motor branch circuits where upstream coordination demands a stiff interrupting rating. Above that it drops: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. ## Undervoltage release and line-protection design It's designed for line protection (not feeder or motor protection), so it's the right choice for a main or sub-main distribution point.","metaTitle":"SENTRON 3VA1112-6EF32-0CA0 MCCB, 3-Pole, 125 A, 220 kA at 24","metaDescription":"SENTRON 3VA1112-6EF32-0CA0 3-pole MCCB, 125 A continuous, 220 kA breaking at 240 V.

The difference is the release: this one carries a TM240 thermal-magnetic release with an undervoltage release, while the 5EE32 variant has a different release configuration.
