Product details

It's a 3-pole unit rated at 40 A continuous, with a TM220 thermal-magnetic overcurrent release that handles both overload and short-circuit conditions without the need for an external trip unit.

Breaking capacity and derating

This MCCB delivers 75.6 kA at 240 V, dropping to 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V. That's a wide voltage band — useful if your panel feeds multiple voltage levels downstream. In a hot enclosure or near a transformer, that derating curve matters for sizing.

Frequently asked questions

What is the breaking capacity of 3VA1140-3EE32-0AA0 at 415 V?

It interrupts 52.5 kA at 415 V, which covers most industrial 400 V distribution systems.

Where can I buy 3VA1140-3EE32-0AA0 and how is it quoted?

We source this part to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is listed here.

Will 3VA1140-3EE32-0AA0 drop into a panel specified around 3VA1110-5ED32-0AA0?

Both are 3-pole SENTRON MCCBs with the same physical footprint (130 x 76.2 x 70 mm), so they share the same mounting and bus-bar spacing. The main difference is the release: this one uses a TM220 thermal-magnetic, while the 3VA1110-5ED32-0AA0 uses a different release. Check the trip curve for your load before swapping.
