Breaking capacity climbs to 187 kA at 240 V AC and holds 121 kA at 415 V AC, then drops to 36 kA at 440 V AC and 17 kA at 690 V AC. That's enough headroom for most low-voltage distribution panels with high fault current at the service entrance.
Rated continuous current Iu is 160 A, and the thermal curve is fully rated at ambient up to 50 °C — at 55 °C it derates to 155.6 A, at 60 °C to 151.2 A, at 65 °C to 146.8 A, and at 70 °C to 142.4 A. IP40 on the front means the breaker face is protected against tools and small wires (1 mm diameter), but not sealed against water — standard for indoor panel mounting. An undervoltage release (UVR) is integrated (order code 3VA9608-0BB25), which will trip the breaker if control voltage drops below the dropout threshold — common for emergency-stop circuits or undervoltage protection on motor feeders. Mechanical endurance is rated at 15,000 operations, typical for a distribution breaker not cycled frequently.
Panel integration
Terminal spread matches the 3VA family pattern; if you're swapping from a 3VA1010-2ED32-0JA0 (100 A frame), verify that the busbar or lug kit accommodates the larger 160 A lugs — the mounting hole pattern and pole spacing are the same across the 3VA frame sizes, so it drops into the same cutout.
