The breaker's short-circuit breaking capacity reaches 242 kA at 240 V and 187 kA at 415 V, with derated values at higher voltages down to 9 kA at 690 V.
Ratings and thermal derating
The breaker derates linearly through higher temperatures: 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. For a panel that runs warm — say 50 °C inside the enclosure — you lose roughly 10 % of the headline current. Plan the load accordingly; the breaker itself is rated for operation up to 70 °C ambient. Short-circuit breaking capacity varies sharply with system voltage. At 240 V it clears 242 kA; at 415 V and 440 V it clears 187 kA; at 500 V it clears 121 kA; at 690 V it clears 9 kA.
The breaker measures 110 mm deep, 138 mm wide, and 248 mm high. That footprint fits standard panel-mount cutouts for 630 A frame MCCBs. The shunt trip release (STL) is factory-fitted — no field assembly of the auxiliary release required. The communication function allows connection to a monitoring system, but the basic switch variant (3VA2463-6JP32-0AA0) is the underlying platform if you need to cross-reference internal parts. Maximum power loss is 162 W at rated load. That heat must be dissipated inside the enclosure; factor it into the panel cooling calculation, especially if the breaker is grouped with other high-current devices.
