It occupies a single 18 mm modular width on the DIN rail, making it a direct fit for standard distribution boards and sub-panels where overcurrent and short-circuit protection is needed for lighting, socket outlets, or small motor circuits. ## What the ratings mean for fit The 50 A rating at 35 °C is the base thermal rating; at 40 °C it derates to 45.95 A, at 45 °C to 43.75 A, at 50 °C to 41.45 A, and at 55 °C to 39.05 A. If the panel ambient runs above 35 °C, the connected load must be reduced accordingly — a 40 A continuous load at 50 °C ambient is fine, but a 48 A load would nuisance-trip. The C-curve means magnetic trip occurs at 5–10× In (250–500 A), suited for moderate inrush loads like small motors or capacitive lighting ballasts. Breaking capacity is 6 kA per EN 60898 — adequate for residential and light commercial panels where the prospective short-circuit current stays under that threshold. For industrial panels with higher fault current, verify the available fault current at the installation point. Overvoltage category III and pollution degree 3 confirm suitability for fixed-installation distribution boards. ## Mounting and integration Snap-on mounting to DIN rail via the quick assembly system; any mounting position allowed. Installation depth is 70 mm, overall depth 76 mm. Width is 18 mm, one modular unit. Combined terminals top and bottom accept busbar and cable connections. IP20 with connected conductors — suitable for enclosed distribution boards, not for wet or washdown areas.","metaTitle":"Siemens 5SY6150-7CC SENTRON MCB, 50 A, 1P, C-Curve, 6 kA","metaDescription":"Siemens 5SY6150-7CC SENTRON miniature circuit breaker, 50 A rated, 1-pole, C characteristic, 6 kA breaking capacity per EN 60898.
