The 4-pole construction occupies 4 modular width units on a DIN rail, with an installation depth of 70 mm and overall dimensions of 72 mm wide × 90 mm high × 76 mm deep. Accepting solid conductors up to 35 mm², it handles the heavier tails common in sub-distribution boards and larger-load final circuits. The mechanical service life of 10 000 operating cycles is typical for a DIN-rail MCB in this class — not a factor that limits specification in normal switching duty. ## Breaking capacity and voltage coverage — what the dual rating means for the panel designer The 5SN6463-8CP lists 6 kA under EN 60898 (the residential / commercial standard) and 10 kA under IEC 60947-2 (the industrial standard). For a panel that must meet a 10 kA SCCR at the load-side terminals, the IEC rating is the one that satisfies the coordination study — not the EN figure. The same part carries both, so there is no ambiguity: the 10 kA value is the binding number for industrial installations. AC voltage coverage spans single-phase and multi-phase operation at 440 V maximum, with a rated supply voltage of 400 V. On the DC side it is rated to 72 V maximum. ## Lifecycle and sourcing posture — current production, no LTB signal This is a standard catalogue item in the SENTRON 5SN family, actively manufactured by Siemens.","metaTitle":"Siemens 5SN6463-8CP SENTRON MCB, 4-pole, 400 V AC, 6/10 kA","metaDescription":"Siemens 5SN6463-8CP SENTRON 4-pole MCB, 400 V AC, 50 Hz, rated 6 kA (EN 60898) / 10 kA (IEC 60947-2).
