Its breaking capacity is 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V — the high interrupt rating at 240 V makes it a fit for large step-down transformer secondaries or high-fault service entrances.
The 160 A rating holds from 40 °C through 50 °C without derating — at 55 °C it drops to 156 A, at 60 °C to 151 A, at 65 °C to 147 A, and at 70 °C to 142 A. Panel cutout and busbar spacing match the 3VA platform.
It includes a shunt trip release (STL) and two auxiliary switches HQ, allowing remote tripping and status feedback.
