At 415 V and 440 V it still clears 242 kA, and at 690 V it holds 17 kA — so the SCCR headroom depends heavily on the system voltage you're working with. That keeps the part simple and reliable for straightforward feeder protection, but if you need adjustable long-time or short-time pickup curves, this isn't the variant. The 192.9 W maximum power loss means the breaker dissipates heat into the enclosure; factor that into your panel thermal budget, especially when mounting multiple breakers side by side. Above 50 °C it derates linearly: 618 A at 55 °C, 607 A at 60 °C, 595 A at 65 °C, and 583 A at 70 °C. That 184 mm width across four poles is standard for this frame size — it occupies the same panel footprint as other 3VA 4-pole breakers in the 315 A class. The breaker mounts with screw terminals; no DIN-rail clip on this frame size. Verify the busbar or cable lug pattern against your existing panel layout before ordering.","metaTitle":"Siemens 3VA1463-7FF42-0AA0 SENTRON MCCB, 315 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1463-7FF42-0AA0 molded case circuit breaker, 315 A rated, 4-pole, TM240 release.
