Product details

MCCB with high interrupting capacity for line protection

The Siemens SENTRON 3VA2440-5HL32-0AC0 is a 3-pole molded case circuit breaker rated at 400 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to 70 °C. Breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V.

The breaker measures 110 mm deep, 138 mm wide, and 248 mm high — a standard MCCB footprint that fits most 3-pole 400 A panel layouts. The 2 HQ auxiliary switches provide status feedback for PLC or indication circuits without needing a separate accessory block.

Maximum power loss of 63.5 W should be factored into enclosure thermal calculations. The line-protection designation means it is optimized for feeder and main-switch duty, not motor or generator protection.

Frequently asked questions

Where can I buy 3VA2440-5HL32-0AC0 and get a price?

This part is sourced to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability.

What is the breaking capacity of 3VA2440-5HL32-0AC0 at 415 V?

121 kA at 415 V, which covers most industrial low-voltage distribution fault levels.

Does 3VA2440-5HL32-0AC0 require derating at elevated ambient temperatures?

No derating needed up to 70 °C — it carries the full 400 A rating from 40 °C through 70 °C.
