Rated insulation voltage is 800 V, and the thermal derating curve stays flat at 80 A up to 50 °C, then drops to 74 A at 70 °C — useful to know when the breaker sits in a warm enclosure next to other heat sources.
Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — fits standard panel-mount cutouts for 4-pole MCCBs in that amp frame. Max power dissipation is 19.2 W at full load, which drives the internal temperature rise in a sealed panel — factor that into the enclosure thermal budget if grouping several breakers.
