Supplementary devices like shunt trips or auxiliary contacts can be added, which simplifies stocking if the panel design later needs remote tripping or status feedback. ## Drop-in fit vs. the 5SL4363-7 — what changes The closest functional peer is the 5SL4363-7, which shares the same 3-pole, C-curve, 400 V AC rating and identical dimensions (76 mm depth, 54 mm width, 90 mm height). The difference is breaking capacity: the 5SL4363-7 is rated 10 kA under both EN 60898 and IEC 60947-2, versus 6 kA for the 5SL6350-7. If the panel was specified around the 5SL4363-7 and the available fault current is under 6 kA, the 5SL6350-7 drops in without rewiring — same footprint, same mounting, same terminal layout. But if the SCCR study calls for 10 kA, stick with the 5SL4363-7. The 5SL6350-7 also runs cooler per pole (3.8 W vs. 5 W at rated current), which helps when the enclosure is tight on thermal budget. ## Panel integration — DIN rail, sealable, halogen-free The sealable design allows locking the breaker handle in the off position for lockout/tagout compliance. The 50/60 Hz frequency range covers both 50 Hz European and 60 Hz North American line frequencies without derating.","metaTitle":"Siemens 5SL6350-7 SENTRON MCB, 50 A, 3-Pole, C-Curve, 6 kA","metaDescription":"Siemens 5SL6350-7 SENTRON miniature circuit breaker, 50 A, 3-pole, C-curve, 6 kA breaking capacity per EN 60898/IEC 60947-2, 400 V AC.
