It occupies 2 modular width units (36 mm) on a DIN rail, with an installation depth of 70 mm and overall depth of 76 mm, so it fits standard residential and light-commercial distribution boards. Breaking capacity of 6 kA at 400 V AC per EN 60898 — this is the standard residential/infrastructure rating; verify the prospective short-circuit current at the installation point doesn't exceed this. The D-curve trips magnetically between 10× and 20× In (250–500 A), so it's sized for loads with a high starting surge, not for general-purpose socket circuits where a B or C curve would be more selective. ## Mounting and integration notes","metaTitle":"Siemens 5SL6225-8CC SENTRON MCB, 2P D 25A 6kA","metaDescription":"Siemens SENTRON 5SL6225-8CC miniature circuit breaker, 2-pole, D-curve, 25 A, 400 V AC, 6 kA per EN 60898.
