Product details

MCCB for 400 A feeder protection

The Siemens 3VA2440-8HL42-0AA0 is a SENTRON 3VA2 molded case circuit breaker rated for 400 A continuous current across its full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. It carries an ETU320 electronic trip unit with an adjustable magnetic short-circuit release spanning 600 A to 4,400 A, so you set the instantaneous pickup to coordinate with downstream devices rather than relying on a fixed magnetic shelf.

Interrupting capacity across voltage classes

This MCCB delivers 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V.

No undervoltage release or shunt trip fitted from the factory (: No), so if you need UVR or MX add-on accessories, those are separate order codes that plug into the accessory slot on the left side of the breaker.

Frequently asked questions

What is the interrupting capacity of 3VA2440-8HL42-0AA0 at 415 V?

330 kA at 415 V, matching the rating at 440 V. At 240 V it reaches 440 kA, and at 690 V it still holds 52.5 kA.

Where can I buy 3VA2440-8HL42-0AA0 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is published here.

Does 3VA2440-8HL42-0AA0 have an undervoltage release built in?

No, the factory configuration does not include an undervoltage release. If UVR is required, it must be ordered as a separate accessory and field-installed.

What is the continuous current rating of 3VA2440-8HL42-0AA0 at elevated ambient temperatures?

Rated 400 A continuously from 40 °C up to 70 °C ambient — no derating required across that entire range.
