Product details

The Siemens SENTRON 3VA2440-6HN32-0AH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 400 A continuously from 40 °C up to 70 °C without derating — that means it holds its full ampacity in a warm panel, not just on a cool bench. Frame size is 4800 A, and the interrupting ratings climb to 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. That spread covers most industrial distribution voltages in North America and Europe on one breaker.

Sizing and mounting

Footprint is 138 mm wide by 248 mm tall by 110 mm deep — fits standard MCCB panel cutouts and bus-bar centers.

Frequently asked questions

Where can I buy 3VA2440-6HN32-0AH0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is 3VA2440-6HN32-0AH0's listed depth?

The depth is 110 mm (4.33 in).

What is 3VA2440-6HN32-0AH0's listed width?

The width is 138 mm (5.43 in).

Will 3VA2440-6HN32-0AH0 drop into a panel that was specified around 3VA2116-5HL32-0AK0 without rewiring?

No — the 3VA2440-6HN32-0AH0 is a 400 A, 4800 A frame breaker, while the 3VA2116-5HL32-0AK0 is a smaller-frame 160 A unit. Panel bus bars, lug sizes, and cutout dimensions differ; a direct swap is not possible without rewiring.
