Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 75.6 kA at 440 V — figures that give the panel builder real selectivity headroom against upstream faults without cascading. The thermal-magnetic curve holds 160 A through 50 °C ambient, then tapers to 150 A at 70 °C. That means the breaker can carry a full 80 A load in a warm enclosure without nuisance tripping — a common pain point when panels are packed tight and ventilation is marginal.
The 3VA1116-6FD42-0AA0 occupies a 101.6 mm wide by 130 mm tall footprint, 70 mm deep — a standard 4-pole MCCB envelope that drops into most SENTRON distribution blocks and panelboards without re-drilling gland plates. Maximum power loss is 38 W, which should be factored into the enclosure's thermal calculation, especially when multiple breakers are ganged in a single cabinet.
