Its interrupting capacity reaches 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V — figures that determine the available fault current the breaker can safely clear without upstream coordination failure. The adjustable thermal-magnetic trip unit covers a range from 945 A minimum to 5 670 A maximum, so it can be tuned to protect a specific feeder or transformer without swapping the breaker frame.
Derating and thermal budget
Continuous current derates with ambient temperature: 630 A at 40 °C drops to 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. Maximum power loss is 162 W, which factors into enclosure ventilation sizing — particularly in a sealed, high-ambient cabinet.
The basic switch is order code 3VA2463-6HL32-0AA0; the -0HH0 suffix adds the factory-fitted accessories above.
Dimensions are 248 mm height, 138 mm width, and 110 mm depth — the depth is the critical dimension for enclosure depth clearance on a standard DIN-rail or backplate mount. The part carries a trip indicator and a voltage trigger for external monitoring.
