This is the rating that governs its fit in a DC distribution panel — not the 1 A continuous rating, but the 10 kA SCCR that tells you it survives a hard short on that battery bank or rectifier output. The C-curve (tripping characteristic class C) means the magnetic trip fires at 5 to 10 times rated current — so for a 1 A breaker, the instantaneous trip threshold sits between 5 A and 10 A. At 18 mm width (1 modular unit), this breaker occupies a single slot on standard DIN rail. ## Environmental and compliance specs Rated for ambient temperatures from -40 °C to 75 °C, with humidity derating: max 95% RH up to 55 °C, tapering to 35% RH at 75 °C.","metaTitle":"Siemens 5SY5101-7CC SENTRON MCB, 1A C-Curve, 220V DC, 10kA","metaDescription":"Siemens SENTRON 5SY5101-7CC miniature circuit breaker, 1-pole, 1A, C characteristic, 220V DC rated, 10kA breaking capacity per IEC 60947-2.

They share the same 18 mm width, 1-pole form factor, and C-curve, but the 5SY4101-7CV cannot be used on a 220 V DC circuit.

It is halogen-free and silicon-free, which supports RoHS and REACH compliance.
