Breaking Capacity and Selectivity Coordination
The 3VA1180-4EF32-0JH0 delivers 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V.
Above that, derating applies: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. In a crowded panel with elevated internal temperatures, size the load circuit to the derated value at the expected ambient — not the 80 A nameplate.
Auxiliary and Trip Configurations
There is no undervoltage release, no ground fault monitoring, no phase failure detection, and no communication function — it is a straightforward line-protection breaker without add-on electronics. A voltage trigger is present for remote signaling.
The 3VA1180-4EF32-0JH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 3-pole footprint matches standard SENTRON 3VA mounting rails; verify the panel cutout and busbar spacing against the 76.2 mm width before committing the BOM.
