Its 25 A rated continuous current holds flat from 40 °C to 50 °C, then derates gradually to 22.5 A at 70 °C — so in a warm enclosure you lose less than 10 % headroom before the 60 °C mark. That keeps the part simple and reliable for a dedicated feeder or branch circuit where you don't need remote monitoring.
Breaking capacity by voltage — where it fits
Short-circuit ratings climb with the system voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. On a 400 V-class panel (common 415 V supply) the 32 kA figure covers most industrial service-entrance and feeder applications.
Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm high — a standard 3-pole MCCB footprint that drops into most SENTRON or 3VA-series mounting bases without rewiring. Three auxiliary switches (HQ type) are built in, giving you status feedback for PLC or indication without an add-on module.
