Product details

What this MCCB carries

The Siemens SENTRON 3VA2040-8HL32-0AA0 is a 3-pole molded case circuit breaker rated for 40 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It uses an ETU320 electronic trip unit, which means you get adjustable overload and short-circuit protection curves, not a fixed thermal-magnetic bimetal. Breaking capacity hits 440 kA at 240 V, 330 kA at 415 V, and still 52.5 kA at 690 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream.

Panel fit and mounting

The 3VA2040-8HL32-0AA0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard MCCB footprint that drops into a SENTRON panel or any DIN-rail-mounting baseplate. Front IP40 keeps dust out of the trip-unit interface; the enclosure is designed for line-side protection in distribution boards. No undervoltage release or communication module on this variant, so it's a straight power path with the trip unit doing the decision-making.

Frequently asked questions

Where can I buy 3VA2040-8HL32-0AA0?

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 the breaking capacity of 3VA2040-8HL32-0AA0 at 240 V?

It is rated 440 kA at 240 V, dropping to 330 kA at 415 V and 52.5 kA at 690 V.

Will 3VA2040-8HL32-0AA0 drop into a panel specified around 3VA1110-5ED32-0AA0?

The 3VA2040-8HL32-0AA0 is a 3-pole MCCB with a 105 mm width, which is the standard SENTRON footprint — it will physically fit the same mounting base and bus connections as the 3VA1110 series, but verify the trip-unit settings and current rating against your BOM; the 3VA1110 uses a different trip platform (ETU or thermal-magnetic depending on variant).
