It carries a continuous current rating of 63 A across the full ambient range from 40 °C to 70 °C (–), which means no derating curve to chase in a warm enclosure; the breaker holds its 63 A all the way up to 70 °C. The interrupting ratings are what decide whether it clears a fault without welding or rupturing: 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. At 690 V the 52.5 kA figure still covers most industrial service-entrance faults. The ETU320 overcurrent release is a solid-state trip unit — adjustable thermal and magnetic settings, so you can fine-tune the long-time pickup and short-time delay to coordinate with downstream breakers. Three poles, insulation voltage rated 800 V, and max power loss of 3 W — the heat dissipation is low enough that you don't need forced ventilation in a standard panel.

Frequently asked questions
Who supplies 3VA2063-8HL36-0AA0 and how is it quoted for volume purchases?
We source this through independent distribution channels and quote it to order against an RFQ. Availability and current pricing are confirmed at quote time — no stock count or price is published here.
What is 3VA2063-8HL36-0AA0's interrupting capacity at 415 V?
330 kA at 415 V. That's the same rating as at 440 V, so it handles the common 400 V class fault levels without a derate.
What compliance documentation does this breaker carry?
As a Siemens SENTRON MCCB, it carries IEC 60947-2 certification for molded case circuit breakers. RoHS and REACH compliance documentation is standard from Siemens for this series. Specific UL/CSA listings depend on the exact variant; verify the nameplate marking for your jurisdiction.
