It is configured for line protection — not motor protection — meaning it is sized for feeder and distribution circuits where the load is primarily resistive or mixed, not a motor starting profile. Breaking capacity is specified at multiple voltage levels: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. For a 32 A frame, the 415 V figure is the one that typically governs in a 400 V distribution panel — 52.5 kA is high enough to handle most utility-fault contributions without cascading upstream.
Thermal derating and endurance
Above that, it derates linearly: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If the panel internal temperature runs hot, account for the derated value rather than the nameplate 32 A. That is typical for a distribution MCCB — fine for infrequent switching, not for a cycling load.
The undervoltage release is factory-fitted; no auxiliary contacts are included (the auxiliary contact version is listed as "Without").
