Its interrupting capacity hits 121 kA at 240 V and 75.6 kA at 415 V — numbers that tell you it handles high-fault industrial feeds, not just branch circuits. No undervoltage release, no ground-fault module, no communication stack: this is a straightforward main or feeder breaker for a panel where remote monitoring is handled elsewhere.
At 70 mm deep, 76.2 mm wide, and 130 mm tall, the 3VA1010-4ED32-0KC0 fits the standard SENTRON 3VA footprint. The 76.2 mm width (three 25.4 mm pole pitches) matches the DIN-rail or mounting-plate pattern used across the 3VA100 frame.
Above that, it derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. Plan the load accordingly; the breaker itself can operate up to 70 °C ambient, but the continuous current you can pass drops.
Auxiliary contacts and shunt trip
The shunt trip lets you remotely open the breaker via a control voltage — useful for emergency-stop circuits or interlocking with upstream gear. No undervoltage release is fitted, so a loss of control voltage will not automatically trip the breaker.
