Its continuous current rating holds at 63 A across the full ambient range from 40 °C to 70 °C — no derating needed as the panel warms up, which simplifies panel layout for high-density enclosures. The interrupting ratings are the headline: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. At 690 V, that 52.5 kA SCCR means it can clear a bolted fault at the full line voltage without cascading upstream — critical for high-fault installations like transformer secondaries or large motor control centers.
The 86 mm depth and 105 mm width fit the standard 3VA fixed-format footprint. If you are replacing an older 3WL or 3VL frame, check the mounting hole pattern — the 3VA uses a different base plate. Panel cutout dimensions are consistent across the 3VA family for the same frame size.
Integration and wiring
Power loss is 3.1 W maximum, which keeps internal cabinet temperature rise low even in dense panels. The 800 V rated insulation voltage (Ui) covers 480/277 V and 600 V systems with margin for surge coordination.
