Product details

SENTRON 3VA1140-5EF32-0AE0 — 40 A MCCB with TM240 Release

It carries a 187 kA interrupting capacity at 240 V, derating to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — numbers that drive the SCCR coordination study for the panel. That makes it a fast-moving standard spare for line protection applications where you don't need the flexibility of an electronic trip. The breaker carries four HQ auxiliary switches (2 NO + 2 NC) built in, so you get status feedback without adding a separate aux block.

Above that, it derates: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C.

Frequently asked questions

Where can I buy the 3VA1140-5EF32-0AE0?

This breaker is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity of this MCCB at different voltages?

The interrupting capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. These values drive the SCCR rating for the downstream panel.

What type of trip unit does the 3VA1140-5EF32-0AE0 use?

It uses a TM240 thermal-magnetic release — fixed, non-interchangeable. No electronic adjustments, no ground-fault or voltage-trip options on this variant.

What auxiliary contacts come with this breaker?

It includes four HQ auxiliary switches (2 NO + 2 NC) integrated into the breaker. No separate aux block purchase needed for basic status feedback.

Will the 3VA1140-5EF32-0AE0 drop into a panel specified for the 3VA1010-2ED32-0JA0 without rewiring?

Both are 3-pole SENTRON 3VA frame breakers, so the mounting footprint and bus-bar spacing are the same family. The difference is the current rating and trip unit — the 3VA1010-2ED32-0JA0 is a lower-current variant with a different release. Verify the load current and trip curve match before swapping.
