Product details

Siemens 3VA1332-6EF32-0DG0 — 320 A SENTRON MCCB with Undervoltage Release

Rated insulation voltage is 800 V, and the thermal current rating holds at 320 A through 50 °C, then derates to 313 A at 55 °C, 306 A at 60 °C, 299 A at 65 °C, and 292 A at 70 °C. That derating curve is the one to check if the breaker sits near other heat sources in a packed enclosure.

That 110 mm depth is the dimension to watch when the breaker mounts in a shallow backpanel or against a gland plate — it fits standard SENTRON 3VA drawout and fixed-mount footprints, so a panel kitted for a 3VA frame will accept this unit without re-drilling.

Frequently asked questions

What is the interrupting rating of 3VA1332-6EF32-0DG0 at different voltages?

220 kA at 240 V, 154 kA at 415 V and 440 V, 121 kA at 500 V, and 17 kA at 690 V. The 690 V figure is the one that limits its use in high-voltage industrial feeds — verify your available fault current against that number.

Where can I buy 3VA1332-6EF32-0DG0?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — send an RFQ for the quantity you need.

Does the 3VA1332-6EF32-0DG0 include an undervoltage release?

Yes. It ships with an undervoltage release (UVR) as the auxiliary release, plus a 1 auxiliary switch and 1 trip alarm switch. No separate UVR module needs to be ordered.
