Its interrupting capacity hits 121 kA at 240 V AC, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V — so it handles high-fault utility feeds and transformer secondaries without cascading upstream. The line protection version means it's configured for feeder and main breaker duty, not motor branch-circuit protection.
Rated continuous current holds at 160 A through 50 °C ambient, then steps down to 155.6 A at 55 °C, 151.2 A at 60 °C, 146.8 A at 65 °C, and 142.4 A at 70 °C.
At 415 V AC the 3VA1216-4EF32-0KH0 is rated for 75.6 kA interrupting capacity, which covers most industrial low-voltage distribution fault levels.
It ships with 2 auxiliary switches plus 1 trip alarm switch (HQ configuration) for status signaling.
