The shunt trip order code is 3VA9688-0BL33 — order that separately if remote trip is needed.
Derating begins at 55 °C (96 A), then 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. Mounting in a sealed, non-ventilated enclosure will raise internal ambient — account for that when loading the breaker near its nameplate.
Mechanical fit and auxiliary wiring
The 3-pole width of 76.2 mm is standard for this frame size — it drops into the same DIN-rail or screw-mount footprint as other 3VA10 frame breakers. The two HQ auxiliary switches are wired via the integrated terminal block; no external add-on module needed for basic N/O and N/C status. Mechanical endurance rated at 15,000 operations — typical for a distribution MCCB not cycled daily.
