Rated continuous current Iu is 125 A, and it holds that rating from 40 °C through 50 °C ambient; above that it derates to 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. For a panel builder, that means the 125 A nameplate is good in a standard 50 °C enclosure — no derate needed unless the ambient climbs higher. Breaking capacity is the headline here: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. The overcurrent release is a TM240 — a thermal-magnetic fixed-trip unit set for 125 A. This is a straightforward, no-frills line-protection MCCB. It does carry a shunt trip (STL) release for remote tripping (part number 3VA9688-0BL32 for the integrated auxiliary trip). No undervoltage release, no auxiliary contact. If you need remote status or undervoltage protection, you'll add those externally.
