Product details

Siemens 3VA1140-6EF32-0AF0 — SENTRON MCCB for Line Protection

It carries a 40 A rated current at 40 °C ambient, holds that rating steady through 50 °C, and derates only to 37 A at 70 °C — useful headroom if the panel runs hot. Breaking capacity is the headline: 220 kA at 240 VAC, 154 kA at 415 VAC, 121 kA at 440 VAC, and 17 kA at 690 VAC.

Fit and Integration

That 70 mm depth is a standard MCCB dimension — it drops into most Siemens SENTRON panelboards and switchgear cubicles without a sub-panel spacer. The width matches the 3VA platform footprint, so existing busbar and lug kits transfer if you're swapping a 3VA1110 or 3VA1112 frame. Integrated auxiliary switch: one auxiliary contact plus one trip-alarm switch (HQ design). The trip indicator is built in — no add-on module needed to signal a fault condition to a PLC or annunciator.
