Product details

Breaking capacity drops with voltage: 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V or 690 V (–). For DC applications, the rated operational voltage is 500 V. The TM240 release means the thermal element is calibrated for a 240 A frame — this breaker is the 25 A tap, so the trip curve is fixed and non-interchangeable in the field.

Panel Integration

Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. Power loss is 8.5 W maximum, so thermal rise inside a sealed cabinet is manageable but should be factored into the cooling budget.

Frequently asked questions

Where can I buy 3VA1125-6EF32-0AA0 and what is the price?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the breaking capacity of 3VA1125-6EF32-0AA0 at different voltages?

At 240 V AC it is 220 kA; at 415 V it is 154 kA; at 440 V it is 121 kA; at 500 V and 690 V it is 17 kA (–). For DC, the rated operational voltage is 500 V.

Will 3VA1125-6EF32-0AA0 drop into a panel specified around 3VA1110-5ED32-0AA0?

Both are 3-pole SENTRON MCCBs with the same 130 x 76.2 x 70 mm footprint, so physical fit is identical. The key difference is the current rating: 25 A on this unit versus the lower-rated 3VA1110-5ED32-0AA0. Verify the load and trip coordination before swapping — the TM240 release is the same frame, so the breaker's interrupting capacity at the applied voltage must also be checked.
