Product details

400 A MCCB with ETU320 — interrupting capacity and thermal derating

The breaker carries the full 400 A up to 50 °C ambient; above that, derate to 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C (–). Maximum power loss is 66 W.

Panel integration — dimensions and mounting

Interrupting ratings at system voltages

Rated short-circuit breaking capacity: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V (–). These values cover most industrial distribution voltages up to 690 V.

Frequently asked questions

What is the closest functional second-source for 3VA2440-6HL32-0CA0?

The peer MPN 3VA1112-5EF32-0CA0 is a smaller-frame 3VA SENTRON MCCB but with a lower continuous current rating and different interrupting capacity — it will not drop into the same panel without verifying the frame size, lug kit, and interrupting requirements. No direct second-source exists; the 3VA2440 frame is specific to the 400 A rating.

Where can I buy 3VA2440-6HL32-0CA0?

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

What are the interrupting ratings of 3VA2440-6HL32-0CA0?

242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V (–).

What compliance documentation does Siemens provide for 3VA2440-6HL32-0CA0?

Siemens typically provides RoHS, REACH, UL, and IEC compliance documentation for the SENTRON 3VA series. Specific certificates should be requested at quote time.
