80 A MCCB with high interrupting capacity for line protection
Its interrupting capacity reaches 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — figures that govern selectivity coordination in high-fault panels.
At 55 °C the continuous current derates to 76.8 A, dropping to 72 A at 70 °C. For panel builders, this means the 80 A frame can be applied at full rating in a 50 °C enclosure; above that, the load or the breaker must be downsized per the published curve.
The 3VA1080-4ED32-0AD0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for this frame size, so it drops into existing SENTRON 3VA panel cutouts without modification.
Auxiliary contacts and release configuration
This variant ships with three auxiliary switches (HQ type) for remote status indication. The auxiliary contacts share the same compact housing; no additional side-mount modules are required for the three-switch configuration.
