That 25 A holds steady up to 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C, so if your panel runs hot you still get full rated current through most of the operating range.
Breaking capacity — what it handles
This 3-pole MCCB delivers 75.6 kA interrupting capacity at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Those numbers tell you it's built for high-fault-current industrial feeders, not light commercial. The 75.6 kA at 240 V covers most North American 277/480 V panelboard applications on the line side; the 52.5 kA at 415 V handles European 400 V distribution. The 690 V rating at 11.9 kA means it can switch 690 V motor circuits in some regions, though you'd check the specific fault study.
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution panels and switchgear without surprises. Maximum power dissipation is 8.5 W, which matters for heat buildup in a packed enclosure.
