Breaking capacity is rated at 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. At 415 V — the most common industrial distribution voltage in IEC territories — the 52.5 kA figure gives solid headroom for high-fault panels without cascading upstream. The 690 V rating (7.5 kA) confirms it can serve 690 V line-side applications, though the steep drop means the fault current available at that voltage must be verified against the installation's prospective short-circuit current.
Above that, derating is gradual: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. For a panel running warm — say 55 °C inside the enclosure — the effective continuous current is still 76.8 A, which keeps the 80 A frame usable for most 63–80 A feeder circuits without upsizing.

Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — a 4-pole frame that fits standard SENTRON panel cutouts.
