Thermal derating is predictable: holds 63 A through 50 °C, drops to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Front IP40 keeps dust and tools out of the breaker mechanism — fine for enclosed switchboards; not rated for washdown.
The 3VA series is Siemens' active MCCB platform, so spares and replacements are available through standard distribution.
No. This variant has no undervoltage release, no ground-fault monitoring, and no communication function — it is a straight line-protection thermal-magnetic breaker.
