Product details

Its interrupting capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream. At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard SENTRON 3VA panel footprints. The IP40 front rating means it's fine for indoor enclosures; no special sealing needed for the switchboard face.

Above that it derates: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.

Built-in undervoltage release and auxiliary contacts

It also carries 2 auxiliary switches HQ (high-qualified) for remote status indication. The integrated auxiliary trip uses order code 3VA9608-0BB25 for replacement. There is no communication module, no phase failure detection, and no ground fault monitoring on this variant. It's a straight line-protection breaker — no bells, no onboard metering. If you need those, you're looking at a different 3VA option.
