It delivers 52.5 kA breaking capacity at 240 V AC, scaling down to 7.5 kA at 690 V — a solid short-circuit rating for most low-voltage switchgear.
The 80 A rating holds flat from 40 °C to 50 °C, then derates gradually to 74 A at 70 °C (–). The 52.5 kA at 240 V is the peak interrupting rating; at 415 V it's 32 kA, still well above typical utility fault levels for a 400 V distribution board. Maximum power loss is 19.2 W — modest for an 80 A frame, so adjacent devices in a DIN-rail row won't see problematic heat buildup.
Integration — what connects where
Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. No undervoltage release — if that's needed, plan an external UVR module.
