The 187 kA at 240 V drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 7.5 kA at 690 V — the SCCR headroom shrinks as line voltage rises, so selectivity studies need to use the voltage-specific value, not the maximum. Continuous current holds at 400 A up to 50 °C ambient; above that it derates to 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C.
Integration and dimensions
The 3VA2340-5KP32-0AG0 measures 248 mm high, 138 mm wide, and 110 mm deep — fits standard panel-mount cutouts for SENTRON 3VA frames. Communication function is onboard, supporting integration into a monitored distribution system. Power loss is 96 W maximum at rated load, so account for that in enclosure thermal calculations.
