It handles 415 V AC across both poles, making it a straight choice for residential and infrastructure subdistribution panels where the load is moderate and the fault level stays under 7.5 kA. The C curve means it tolerates inrush currents 5 to 10 times the 50 A rating before tripping magnetically — sized for mixed lighting and general-purpose circuits that see brief startup draws. On a 50 A circuit, that's 250 to 500 A instantaneous trip threshold; thermal protection handles sustained overloads. Two modular width units (36 mm) snap onto standard DIN rail. ## How the 5SL6250-7RC compares to the 5SL6550-7BB The closest functional peer in the SENTRON 5SL6 family is the 5SL6550-7BB. Both are 50 A, 2-pole, C-curve MCBs in the same 36 mm wide, 76 mm deep housing. The key difference: the 5SL6250-7RC carries a higher breaking capacity — 7.5 kA per EN 60898 versus 6 kA on the 5SL6550-7BB. Below 6 kA, either works; above 7.5 kA, neither does — step up to a higher-rated series. The 5SL6550-7BB also includes neutral conductor switching and derating data at elevated ambient temperatures (46.19 A at 40 °C, 39.81 A at 55 °C) that the 5SL6250-7RC listing does not explicitly publish, though the thermal behavior should be similar given the same enclosure and pole count. Halogen-free and silicon-free construction, so it won't off-gas corrosive compounds under fault conditions.","metaTitle":"Siemens 5SL6250-7RC SENTRON MCB, 50 A, 2-Pole, C Curve, 7.5","metaDescription":"Siemens SENTRON 5SL6250-7RC miniature circuit breaker, 50 A, 2-pole, C characteristic, 7.5 kA breaking capacity per EN 60898.
