At 36 mm wide (2 modular units), it occupies the same footprint as any other 1P+N 2-MW breaker — no surprises when swapping into an existing SENTRON or third-party distribution board.","metaTitle":"Siemens 5SJ6516-6KS SENTRON MCB, 1P+N, B Curve, 16 A, 6 kA","metaDescription":"Siemens SENTRON 5SJ6516-6KS miniature circuit breaker, 1P+N, B characteristic, 16 A rated, 6 kA breaking capacity per EN 60898.
