At 415 V the 75.6 kA interrupting rating gives solid SCCR headroom for most industrial panel designs. At 240 V it jumps to 121 kA, so it handles high-fault service-entrance applications as well. The 800 V rated insulation voltage supports 690 V line-to-line systems, with a 52.5 kA break at 440 V and 11.9 kA at 500 V and 690 V. That means it coordinates cleanly with downstream branch breakers across common voltage levels — a key consideration for selectivity studies.
The 80 A rating holds flat from 40 °C through 50 °C, then derates gradually to 74 A at 70 °C. That thermal curve means you don't lose capacity in a warm enclosure unless ambient exceeds 50 °C. Dimensions are 130 mm tall, 76.2 mm wide, 70 mm deep — a compact 3-pole footprint that fits standard panel layouts.
