What this MCCB does for your panel
Its ETU320 electronic trip unit gives you adjustable long-time delay (0.5 to 17 s) and N-conductor protection configurable to OFF, 50%, or 100% of phase current, so it handles both three-phase and single-phase line-to-neutral faults in a single package. The interrupting ratings are substantial: 440 kA at 240 V, 330 kA at 415 V, and 53 kA at 690 V, meaning it can clear high-fault-current events without cascading upstream in most distribution panels.
The 3VA2110-8HL42-0AA0 measures 181 mm high, 140 mm wide, and 86 mm deep — a compact 4-pole MCCB that fits standard distribution panelboards. Maximum power loss is 7.7 W, which is modest enough that you don't need forced ventilation in a typical 200 A panel, but worth checking against your enclosure's thermal budget if you're packing several breakers side by side.
