The Siemens SENTRON 5SL4350-6 is a 3-pole miniature circuit breaker with a B-curve trip characteristic, rated 50 A at 400 V AC. It delivers a 10 kA breaking capacity per both EN 60898 and IEC 60947-2, covering most residential and light commercial panelboard specs.
Rated for 10 000 mechanical operating cycles typical, with IP20 protection when conductors are connected. Halogen-free and silicon-free construction suits environments sensitive to outgassing.
The 5SL4363-7 is the same 3-pole SENTRON platform but with a C-curve trip characteristic and slightly higher per-pole power loss (5 W vs 4 W). It drops into the same panel footprint without rewiring.
The depth is 76 mm, with an installation depth of 70 mm.
The width is 54 mm, equivalent to 3 modular width units.
Yes. Both breakers share the same 76 mm depth, 54 mm width, 90 mm height, 3-pole design, and 10 kA breaking capacity. The only functional difference is the trip curve — B versus C — so no mechanical or wiring changes are needed.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
