Its interrupting rating hits 75.6 kA at 240 V — enough for high-fault utility feeds — and derates through 52.5 kA at 415 V and 32 kA at 440 V, with 11.9 kA holding at 500 V and 690 V. That SCCR headroom means it coordinates cleanly downstream of a larger main breaker without cascading failure.
The 80 A rating holds flat from 40 °C through 50 °C, then tapers to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That gives remote trip capability and status feedback — useful for a PLC-based distribution monitoring scheme or emergency-off circuit. No undervoltage release or ground-fault module is fitted, so if those are needed they must be added externally.
Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB envelope that fits most DIN-rail or panel-mount distribution boards. The 70 mm depth leaves room behind a 200 mm deep enclosure for wiring and finger-duct clearance. Power loss is 19.2 W maximum, so factor that into the enclosure thermal budget if grouping several breakers.
