That interrupting rating drops to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V — so the real-world SCCR you spec against depends entirely on your system voltage. At 40 °C it carries the full 630 A; derate linearly through 70 °C where it holds 520 A. The 110 mm depth (4.33 in) is the dimension that matters for enclosure depth clearance; the 138 mm width (5.43 in) sets the DIN-rail pitch. That's still high enough for virtually any distribution board downstream of a 2 MVA transformer — you'll get full selectivity with upstream fuses or a larger-frame MCCB. The shunt trip (STL) lets you remote-trip via a PLC or emergency-stop circuit; the two auxiliary switches plus trip alarm give you status feedback for SCADA or local indication.","metaTitle":"Siemens 3VA2463-6HN32-0JH0 SENTRON MCCB, 630 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-6HN32-0JH0 molded case circuit breaker, 630 A rated at 40 °C, 242 kA breaking at 240 V. 3-pole, line protection design with shunt trip.
