Product details

Frame rating and interrupting capacity — the numbers that govern selectivity

The Siemens SENTRON 3VA2440-5HN32-0KH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 400 A across the full ambient range from 40 °C through 70 °C — no derating needed up to that ceiling. The interrupting capacity is what drives coordination: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 9 kA at 690 V.

Auxiliary and release configuration — what ships inside the cover

Physical fit — dimensions for panel layout

That 138 mm width is the standard 3-pole MCCB footprint for the SENTRON 3VA2 frame at this rating — it occupies the same panel cutout as other 3VA2 3-pole units, so a panel laid out for a 3VA2116-5HL32-0AK0 will accept this 400 A frame without re-drilling the mounting plate. The 110 mm depth includes the arc-chamber housing; allow clearance for the shunt-trip wiring and auxiliary cable exit at the top.

Frequently asked questions

Where can I buy 3VA2440-5HN32-0KH0 and what is the lead time?

This 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 the latest lead time.

Will 3VA2440-5HN32-0KH0 drop into a panel specified around 3VA2116-5HL32-0AK0 without rewiring?

Both are 3-pole SENTRON 3VA2 breakers sharing the same 138 mm width and DIN-rail mounting pattern, so the panel cutout and bus-bar spacing are identical. The 400 A frame is taller (248 mm vs the smaller frame height) — verify vertical clearance in the enclosure before swapping.
