Its interrupting capacity reaches 121 kA at 240 V AC, 75.6 kA at 415 V, and still holds 11.9 kA at 690 V — so it handles high-fault scenarios downstream of a transformer or in a main feeder position without needing an upstream current-limiting fuse. The 25 A rating holds steady from 40 °C up to 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C. For a panel running warm near the top of a cabinet, that derating curve means you don't have to oversize the frame — just account for the ambient temp when setting the load.
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or backplate mounting schemes.
