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. 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.

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).
