It is configured for line protection — no ground-fault monitoring, no phase-failure detection, no communication module. The interrupting ratings are 121 kA at 240 V, 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 large motor branch circuits where the available fault current is substantial. The auxiliary contact block is a 2+1 HQ configuration (two auxiliary switches plus one trip-alarm switch), and the integrated shunt trip (STL) release is order code 3VA9688-0BL30. The N-conductor protection is set to 100%, meaning the neutral pole is fully rated and switches with the phase poles — important for 4-wire systems where the neutral carries load current.
Above that it derates: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C. Dimensions are 140 mm wide × 158 mm high × 70 mm deep.
