Breaking capacity hits 440 kA at 240 V, 330 kA at 415 V, and still carries 52.5 kA at 690 V, so it handles high-fault scenarios without cascading upstream. The ETU350 gives you adjustable long-time, short-time, and instantaneous pickup settings — useful for coordinating with downstream breakers in a selective distribution board.
Panel fit and deployment context
The 3VA2216-8HN32-0AA0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA frame size that drops into existing 3VA panel cutouts without re-drilling. Power loss runs 19.7 W at full load — factor that into your enclosure thermal budget if you're packing multiple breakers in a row.
Environmental limits
The storage minimum is the real shipping limit — no special cold-chain handling needed for winter freight.
