That's unusual for a compact MCCB — many competitors start derating above 40 °C. At 240 V it's rated 187 kA, so it handles utility-transformer secondary faults cleanly. No undervoltage release, no shunt trip, no communication module on this order code; it's a straight thermal-magnetic motor protector with auxiliary switches (3 HQ aux switches included per). The basic switch inside is 3VA21405MN320AA0, so if you're swapping just the internal mechanism, that's the spare part number.
That's a standard SENTRON 3VA2 frame size — mounts on DIN rail or direct panel via screw terminals.
Maximum power loss is 1.6 W at rated load. That's low enough that you don't need forced ventilation in a typical panel — the heat rise from this breaker alone won't push the internal ambient past the 70 °C operating limit.
