Product details

Thermal derating and panel fit

The 3VA1225-6EF32-0AG0: The 250 A rating holds flat from 40 °C to 50 °C; above that it derates smoothly to 223 A at 70 °C. That matters when the breaker lives in a crowded enclosure — if ambient inside the panel hits 60 °C, you lose 13 A of headroom. Dimensions are 158 mm high, 105 mm wide, 70 mm deep, so it fits standard MCCB mounting footprints. The auxiliary switch configuration is 1 auxiliary + 1 trip alarm (HP type), which gives a separate signal for fault vs. manual open.

Frequently asked questions

Where can I buy 3VA1225-6EF32-0AG0 and how do I get a price?

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

What is 3VA1225-6EF32-0AG0's interrupting rating at 240 V?

220 kA at 240 VAC. At 415 V it is 154 kA, at 500 V it is 30 kA, and at 690 V it is 17 kA.

What is the rated current of 3VA1225-6EF32-0AG0 at 40 °C?

250 A at 40 °C, holding flat through 50 °C, then derating to 223 A at 70 °C.

Will 3VA1225-6EF32-0AG0 drop into a panel specified around 5SQ2370-2YA05 without rewiring?

The 3VA1225-6EF32-0AG0 is a 3-pole MCCB with a 250 A TM240 release; the 5SQ2370-2YA05 is a different manufacturer's part. Mounting dimensions and bus-bar centers may differ — verify physical fit before substitution.
