Product details

It's built for line protection — the standard job of a distribution MCCB in a panel — and carries interrupting ratings that climb to 75.6 kA at 240 V, 52.5 kA at 415 V, and still 10.5 kA at 690 V. That kind of headroom means it clears high-fault bolted faults without cascading upstream, which is the main reason you spec a SENTRON over a miniature breaker.

At 55 °C it drops to 19.2 A, and at 70 °C it's 18 A. No trip indicator, no auxiliary contacts, no undervoltage release — this is a bare-bones line-protection breaker with the shunt trip as the only accessory. If you need status feedback, you'll add the external auxiliary trip (order code 3VA9688-0BL30).

The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard SENTRON 3VA footprint that fits the DIN-rail or screw-mount pattern in most distribution boards. The 3-pole body takes up three module widths on the rail.

Frequently asked questions

Where can I buy 3VA1120-3EF32-0HA0 and how do I get a price?

The part is sourced and quoted 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.

When sourcing 3VA1120-3EF32-0HA0, what's the closest functional second-source?

The closest functional peer in the SENTRON family is the 3VA1110-5EE32-0JA0, but it has a different overcurrent release and accessory configuration. Verify the trip curve and shunt trip compatibility before substituting — it's not a guaranteed drop-in.

What is 3VA1120-3EF32-0HA0's listed depth?

The depth is 70 mm, with a width of 76.2 mm and a height of 130 mm.

What compliance documentation does this breaker provide?

The evidence does not list specific compliance documents (RoHS, REACH, UL, IEC) for this order code. The part is a Siemens SENTRON MCCB, which typically carries IEC 60947-2 certification, but you should request the declaration from the supplier at quote time.
