At 415 V and 440 V it still breaks 187 kA, dropping to 121 kA at 500 V and 3.7 kA at 690 V, so the voltage class of your system determines the available fault current it can safely clear. ## Integration — Panel Fit and Mounting The 3VA2140-6HM32-0AA0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard footprint for SENTRON 3VA frame sizes. Poles: 3. Interrupting capacity: 242 kA at 240 VAC, 187 kA at 415/440 VAC, 121 kA at 500 VAC, 3.7 kA at 690 VAC. Insulation voltage: 800 V. Operating temperature: -25 °C to +70 °C.
