Product details

It carries a 220 kA breaking capacity at 240 VAC — that is the SCCR headroom for fault clearing at that voltage level, which governs selectivity coordination with downstream breakers. At 415 VAC the interrupting rating is 154 kA, dropping to 121 kA at 440 VAC, and 17 kA at both 500 VAC and 690 VAC.

Thermal Derating and Continuous Current

At 55 °C it derates to 39 A, holds 39 A at 60 °C, then drops to 38 A at 65 °C and 37 A at 70 °C (–).

The 3VA1140-6EF32-0AB0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 3-pole footprint matches the SENTRON 3VA family; if replacing an existing 3VA1110 variant, verify the lug kit and accessory slot compatibility — the auxiliary switch design here is 2 auxiliary switches HP, which occupies the same accessory bay as the 3VA1110 series.

Frequently asked questions

What is the breaking capacity of 3VA1140-6EF32-0AB0 at 480 VAC?

The closest published rating is 121 kA at 440 VAC. For a 480 V system, use the 440 V figure as the conservative interrupting rating; the breaker is not separately rated at 480 V.

Where can I buy 3VA1140-6EF32-0AB0?

This part is sourced to order against an RFQ through independent distribution channels. Submit a request for current pricing and availability; lead time and stock position are confirmed at quote time.

Will 3VA1140-6EF32-0AB0 drop into a panel specified around 3VA1110-5ED36-0AC0?

Both are 3-pole SENTRON MCCBs on the same DIN-rail footprint, so the physical swap is straightforward. However, the 3VA1140 carries a TM240 thermal-magnetic release versus the 3VA1110's release type; verify the trip curve and continuous current rating match the branch circuit requirements before substituting.
