Current Ratings and Thermal Derating
Above that, it derates linearly: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C.
Interrupting Capacity by Voltage
The 3VA2340-5JP32-0BL0 delivers 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. For a 480 V panel, the 75.6 kA rating gives good SCCR headroom for most motor control centers. At 690 V the capacity drops to 7.5 kA — verify your available fault current if applying on a 690 V system.
The 110 mm depth leaves room for rear-access cabling in a typical 600 mm deep enclosure.
