Product details

The Siemens SENTRON 3VA1225-5EE32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous at 40 °C, with a TM220 thermal-magnetic overcurrent release — the '22' indicating the magnetic trip is fixed at 220 A. It's designed for line protection in distribution panels where you need high fault interruption: 187 kA at 240 V, 121 kA at 415 V, and still 17 kA at 690 V.

Interrupting ratings and thermal derating

At 415 V it still clears 121 kA, which covers most industrial secondary distribution. The thermal curve is flat from 40 °C to 50 °C (full 250 A), then drops to 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. If this panel lives in a hot mezzanine, size the load for the derated value at your ambient.

Frequently asked questions

Where can I buy 3VA1225-5EE32-0AA0 and get a price?

This part is sourced through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time.

Will 3VA1225-5EE32-0AA0 drop into a panel specified around 3VA1112-5EE32-0AA0?

The 3VA1225 and 3VA1112 share the same SENTRON 3VA platform and similar mounting footprint, but the 1225 is a larger frame rated for 250 A vs the 1112's lower rating. The bus connections and lug kit may differ — verify the lug kit before swapping.

What are the key interrupting ratings for this MCCB?

187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V.
