Siemens SENTRON 3VA2110-7KP42-0AA0 — 100 A MCCB with ETU850 Trip Unit
It carries an ETU850 electronic trip unit, adjustable from 150 A up to 1 200 A, giving you flexibility to match the breaker to the actual load without swapping hardware. Breaking capacity is 330 kA at 240 V AC, dropping to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. That's unusual; most breakers start tapering above 40 °C.
Panel Fit & Mounting
The 140 mm width is the standard 4-pole MCCB footprint — it occupies four 35 mm DIN spaces if mounted on a rail, or bolts directly into a panel backplate. The trip indicator is also absent on this build, so fault status comes through the communication interface rather than a local flag.
