Product details

It's built for line protection — feeding a main bus, a distribution panel, or a large motor control center. That matters when the panel runs hot and you need the breaker to hold without nuisance tripping.

The 3VA series is Siemens' current-generation MCCB platform. If the BOM calls for a 320 A 4-pole with a fixed thermal-magnetic curve, this is a direct fit.

Dimensions: 248 mm tall, 184 mm wide, 110 mm deep. Keep it inside the enclosure, not on the door. That's not trivial — if you're packing a dozen of these in a panel, factor that heat into the ventilation budget. The storage spec governs handling and shipping, not running.

What it doesn't have — and why that's fine

This is a plain-vanilla line-protection MCCB. If you need adjustable trip curves or remote monitoring, look at the 3VA electronic-trip variants. But if the spec says '320 A, 4-pole, thermal-magnetic, line protection,' this is the exact part.

Frequently asked questions

How do I get pricing and availability for 3VA1332-5GF42-0AA0?

Submit an RFQ. This part is sourced to order through independent distribution; current pricing and stock status are confirmed at quote time. No automated price or lead time is published here.

What are the key ratings of 3VA1332-5GF42-0AA0?

Rated 320 A continuous, 4-pole, TM240 thermal-magnetic release. Breaking capacity: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, 11.9 kA at 690 V. Insulation voltage 800 V. IP40 front protection.

Will this MCCB fit in a panel designed for 5SQ2670-2YA63?

Physical dimensions are similar (248 x 184 x 110 mm) and both are 4-pole MCCBs, but the 5SQ2670 series is a different Siemens platform. The mounting footprint may be the same, but verify DIN-rail or screw-hole spacing against your panel layout before committing. No direct interchangeability claim is made here.

Does the 3VA1332-5GF42-0AA0 have UL or IEC certifications?

The evidence lists no specific certification marks (UL, CSA, CE) for this order code. As a Siemens SENTRON product, it is typically designed to IEC 60947-2, but confirm the exact certification status with the manufacturer or your local Siemens representative before specifying.
