Siemens 3VA2063-6HL32-0AE0 — 63 A MCCB with ETU320, active production
The ETU320 is an electronic overcurrent release with no communication function, no undervoltage release, and no ground-fault monitoring — it is a straight line-protection trip unit.
Above that, the continuous current derates per the datasheet curve: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C. Maximum power dissipation is 5.4 W.
Front-face protection class is IP40. The breaker accepts a supplied basic switch (order code 3VA2063-6HL32-0AA0) and has no voltage trigger or phase-failure detection.
