Breaking capacity is 6 kA per both EN 60898 and IEC 60947-2, so it coordinates with downstream loads in residential and light commercial distribution boards where the prospective fault current stays under that threshold. The C-curve (rated 50 A) trips between 5× and 10× In, making it a standard choice for mixed resistive and moderate inductive loads — lighting circuits, small motor branch circuits, and general-purpose socket outlets — where inrush isn't severe enough to need a D-curve. Thermal derating is published: 46.97 A at 40 °C, 45 A at 45 °C, 42.01 A at 55 °C. Width is 36 mm (2 modular units), depth 76 mm, height 90 mm. Installation depth 70 mm. Mounts in any position on standard DIN rail. Sealable (tamper-evident cover available) and halogen-free / silicon-free construction — relevant for installations with strict off-gassing requirements (hospitals, clean rooms, data centers). Mechanical service life 10,000 operating cycles typical. Energy limitation class 3.","metaTitle":"Siemens 5SL6550-7 SENTRON MCB, 1P+N, C-curve, 50 A, 6 kA","metaDescription":"Siemens 5SL6550-7 SENTRON miniature circuit breaker, 1P+N, C-curve, 50 A rated at 230 V AC, 6 kA breaking capacity per EN 60898.
