Product details

The Siemens SENTRON 3VA1120-6EE32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 20 A continuous current across a 40 °C to 55 °C ambient range, derating to 19 A at 60 °C and above.

Dimensions: 130 mm height, 76.2 mm width, 70 mm depth — fits standard 3-pole MCCB cutouts. Front face carries IP40 protection; the enclosure is not rated for washdown environments.

The breaking capacity is the headline number for this class: 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V.

Frequently asked questions

How do I get current pricing and availability for 3VA1120-6EE32-0AA0?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through independent distribution channels.

What is the breaking capacity of 3VA1120-6EE32-0AA0 at 240 V?

220 kA at 240 V AC, making it suitable for high-fault-current applications like transformer secondaries.

Will 3VA1120-6EE32-0AA0 drop into a panel specified around 3VA1110-5ED32-0AA0?

Both are 3-pole SENTRON 3VA breakers with the same 70 mm depth and 76.2 mm width, so the footprint is identical. The key difference is the overcurrent release: 3VA1120-6EE32-0AA0 uses a TM220 (20 A fixed thermal-magnetic), while 3VA1110-5ED32-0AA0 uses a different release. Verify the trip curve and amp rating match your branch circuit before swapping.
