Product details

The interrupting capacity at 240 V AC is 187 kA, dropping to 121 kA at 415 V AC, 75.6 kA at 440 V AC, and 17 kA at 690 V AC. These ratings are for AC networks; for DC applications, consult the 3VA device manual.

Above that, the continuous current drops linearly: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. Front IP40 protection means it is suitable for general indoor panel environments but not washdown areas. Dimensions are 76.2 mm wide, 130 mm high, 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration.

The 3VA1140-5EF36-0AB0 is a current-production Siemens SENTRON MCCB.

Frequently asked questions

What is the interrupting capacity of 3VA1140-5EF36-0AB0 at 415 V?

At 415 V AC the interrupting capacity is 121 kA. At 240 V it is 187 kA, at 440 V it is 75.6 kA, and at 690 V it is 17 kA.

Will 3VA1140-5EF36-0AB0 drop into a panel specified around 3VA1010-2ED32-0JA0 without rewiring?

No. The 3VA1140-5EF36-0AB0 is a different frame size with different mounting dimensions and terminal arrangements. It is not a form-fit-function substitute for the 3VA1010-2ED32-0JA0. Panel layout and bus connections would need to be reworked.

Where can I buy 3VA1140-5EF36-0AB0 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is published here.
