That's the spec that decides fit for a main or subfeed breaker in a large industrial switchboard.
Thermal derating and enclosure planning
Rated current holds at 16 A from 40 °C up to 55 °C (cite:–), then derates to 15 A at 60 °C and above (cite:–). The 70 mm depth (cite:) and 76.2 mm width (cite:) fit standard MCCB mounting footprints; the 10.6 W max power loss (cite:) is manageable but adds up in a densely packed panel.
Rated insulation voltage 800 V (cite:). Interrupting capacity drops with voltage: 75.6 kA at 440 V (cite:), 17 kA at 500 V and 690 V (cite:–). Three auxiliary switches HQ are built in (cite:).
