Product details

It carries an 85 kA Icu at 220/240 V AC and 36 kA at 380/415 V AC, both per IEC 60947-2 — meaning it can safely interrupt fault currents up to those levels without upstream cascading.

The F breaking capacity code (36 kA at 415 V) positions this breaker for downstream distribution in a 415 V system with a higher-rated upstream device. At 690 V the Icu drops to 8 kA — enough for most 690 V motor circuits but not for high-fault locations. The 125 A rating at 40 °C and 50 °C means the trip unit holds its full rating at typical panel ambient; no derating needed unless you push past 50 °C.

The 140 mm width and 161 mm height fit standard MCCB cutouts; 86 mm depth leaves room for rear-access wiring. IP40 enclosure is fine for clean indoor switchgear but not washdown areas.
