The Siemens SENTRON 5SL4316-6 is a 3-pole miniature circuit breaker rated 16 A with a B tripping characteristic, designed for 400 V AC systems at 50/60 Hz. The B-curve (3–5× In instantaneous trip) suits resistive and lighting loads where inrush is low; for motor or transformer circuits you would reach for a C-curve sibling like the 5SL4363-7. Halogen-free and silicon-free molding suits environments where outgassing matters, such as HVAC or clean-build panels. Power loss per pole is 1.8 W at rated current in hot operating state, so a 3-pole unit dissipates roughly 5.4 W — factor into enclosure thermal rise if you are packing several breakers in a sealed box.

Frequently asked questions
What is the difference between 5SL4316-6 and 5SL4363-7?
Both are 3-pole SENTRON MCBs with the same 400 V AC, 10 kA rating, dimensions (76×54×90 mm), and 10 000-cycle mechanical life. The 5SL4316-6 uses a B-curve (3–5× In) for resistive/lighting loads; the 5SL4363-7 uses a C-curve (5–10× In) for moderate inrush loads like small motors or transformers. They are mechanically interchangeable in the same DIN-rail panel if the trip curve matches the circuit.
What is the depth of 5SL4316-6?
The depth is 76 mm; installation depth is 70 mm. Width is 54 mm (3 modular units), height is 90 mm.
