It occupies a single modular width unit (18 mm) on a DIN rail, making it a direct fit for standard residential and infrastructure distribution boards where DC branch circuit protection is required. Snap-on mounting to a standard DIN rail, any position. Depth is 76 mm with 70 mm installation depth behind the panel surface. The IP20 rating (with connected conductors) means it is intended for enclosed distribution boards, not exposed outdoor or washdown locations. Sealable design allows lockout/tagout for isolation procedures. Halogen-free and silicon-free construction avoids corrosive outgassing in sensitive environments. The C-curve (tripping characteristic class C) means the magnetic trip activates at 5 to 10 times rated current — suited for moderate inrush loads like small DC power supplies, lighting ballasts, or control transformers. Overvoltage category III and pollution degree 2 confirm suitability for fixed-installation distribution panels. The 125 VDC rating is per pole; for higher DC voltages, series connection of poles is required (not covered by this single-pole unit).","metaTitle":"Siemens 5SL5103-7CC SENTRON MCB, 1P C3, 125 VDC, 10 kA","metaDescription":"Siemens SENTRON 5SL5103-7CC miniature circuit breaker, 1-pole, C-curve, 3 A, rated 125 VDC with 10 kA breaking capacity.

The 5SL6120-7 is an AC-rated unit (400 V, 6 kA), while the 5SL5103-7CC is DC-rated (125 V, 10 kA).
