SENTRON 3VA1140-5EF32-0JC0 — 40 A MCCB with shunt trip, 187 kA IC at 240 V
The 121 kA at 415 V and 75.6 kA at 440 V still cover most industrial distribution panels. At 500 V and 690 V the rating drops to 17 kA, so verify your available fault current if this breaker lands on a 480 V or 600 V bus. Two HQ auxiliary switches are also installed, giving you status feedback (open/closed) for the PLC or panel indication without adding a separate accessory block. The breaker is 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard SENTRON 3VA footprint that fits the same panel cutouts and busbar arrangements as other 3VA frame sizes.
At 55 °C it drops to 39 A, at 65 °C to 38 A, and at 70 °C to 37 A. No undervoltage release is fitted, and no ground-fault monitoring version is included. If you need UVR or GF protection, you would add an external module or select a different 3VA variant. The breaker has no communication function — it is a standalone thermal-magnetic MCCB, not a smart breaker.
