If your installation has a transformer closer than about 10 m of cable, verify the PSC at the board; you may need the 10 kA variant. The 76 mm depth plus 70 mm installation depth means the breaker body extends 70 mm behind the DIN rail — verify the enclosure depth if retrofitting into a shallow consumer unit. The neutral conductor is not switched — this is a 2-pole breaker that switches both phases (line and line) on a split-phase or two-phase system; for a single-phase application with a switched neutral, use a 1P+N variant.","metaTitle":"Siemens 5SL6250-7MB SENTRON MCB, 2P C 50A 6kA 400V","metaDescription":"Siemens 5SL6250-7MB SENTRON miniature circuit breaker, 2-pole, C-curve, 50 A rated, 6 kA breaking capacity at 400 V AC.

However, the 5SL6016-7KL is a 1-pole B-curve 16 A breaker, while the 5SL6250-7MB is a 2-pole C-curve 50 A — verify the circuit's voltage, current, and fault-level requirements before substitution."},{"question":"What compliance documentation does Siemens provide for the 5SL6250-7MB?","answer":"The 5SL6250-7MB is designed to EN 60898 (breaking capacity of 6 kA at 400 V AC) and carries the SENTRON brand.
