It carries an ETU320 electronic trip unit — a basic adjustable thermal-magnetic release — and is built for high-fault applications: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and still 40 kA at 690 V.
Above that it derates linearly: 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C.
Auxiliary contacts and integration
This variant ships with 4 auxiliary switches (HQ type) — enough for remote status indication, interlocking, or PLC feedback without adding a separate module. The auxiliary release slot is empty (no shunt or undervoltage release fitted), and there is no ground-fault monitoring module. If you need those, the basic switch platform is 3VA2440-6HL32-0AA0, and the integrated auxiliary trip is 3VA9608-0BB24. The breaker is 138 mm wide, 248 mm high, and 110 mm deep — standard SENTRON 3VA 400 A frame footprint, so it drops into existing panel cutouts and busbar arrangements for the series.
