Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — that SCCR headroom means it can sit upstream in a high-fault panel without cascading a trip.
Current and temperature derating
Above that it derates: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C.
No rewiring needed if swapping from another 3VA 3-pole with the same lug pattern.
Auxiliary and release configuration
Comes with an integrated undervoltage release (UVR) — part number 3VA9608-0BB11 — and a trip indicator. The auxiliary contact block includes 2 normally-open/normally-closed switches plus one dedicated trip alarm switch. No communication function, no phase failure detection, no voltage trigger.
