Its 15 kA breaking capacity per IEC 60947-2 means it can safely interrupt fault currents up to that level without upstream damage — a figure that governs selectivity coordination in distribution panels. The C-curve (5–10× In) suits it for mixed resistive and moderate inductive loads like control transformers and small motor circuits where inrush is present but not extreme. Rated operating voltage is 230 V AC single-phase, with a maximum of 250 V AC single-phase. For DC applications, the maximum operating voltage is 72 V DC. The breaker is designed for AC supply only (50/60 Hz). ## Mounting and integration Snaps onto DIN rail via the quick assembly system. Width is 18 mm (1 modular unit), depth 76 mm, installation depth 70 mm. Mounting position is unrestricted. The IP20 rating applies with connected conductors — standard for enclosed panel installation. Pollution degree 3 and overvoltage category III suit it for fixed industrial distribution boards where transient overvoltages are expected. Combined terminals top and bottom accept the same conductor range. Sealable design allows locking the cover to prevent tampering. Halogen-free and silicon-free construction matters for environments sensitive to outgassing — clean rooms, semiconductor fabs, or food processing lines.","metaTitle":"Siemens 5SY4101-7CV MCB, 1P C1, 15 kA IEC 60947-2","metaDescription":"Siemens 5SY4101-7CV miniature circuit breaker, 1-pole C-curve 1 A, 15 kA breaking capacity per IEC 60947-2.
