Product details

SENTRON 3VA1220-5MH32-0AA0 — 200 A MCCB with TM120M Release

The 200 A rating holds flat from 40 °C through 50 °C ambient, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C — so in a warm panel you lose about 12% of capacity at the top of the operating range. Interrupting capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. The 690 V figure of 4.5 kA is more modest, so if your application is a 690 V distribution board, verify the SCCR coordinates with your upstream transformer.

Frequently asked questions

What is the interrupting capacity of 3VA1220-5MH32-0AA0 at 240 V?

At 240 V AC, the interrupting capacity is 187 kA. At 415 V it is 121 kA, at 440 V it is 75.6 kA, at 500 V it is 30 kA, and at 690 V it is 4.5 kA.

Where can I buy 3VA1220-5MH32-0AA0 and how is it quoted?

This part is sourced to order against an RFQ through independent industrial distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for your quantity and target delivery window.

Will 3VA1220-5MH32-0AA0 drop into a panel designed for 3VA1112-5EE32-0AA0?

Both are 3-pole SENTRON MCCBs sharing the same 105 mm width and 70 mm depth, so the physical footprint is identical. The key difference is the overcurrent release: this unit uses a TM120M thermal-magnetic release, while the 3VA1112-5EE32-0AA0 uses a different release type. Verify the release curve matches your coordination study before swapping.
