It protects final circuits in residential and light commercial infrastructure where the B-curve's magnetic trip threshold (3 to 5 times In) suits resistive and general-purpose loads with modest inrush — think lighting, socket outlets, and small appliances rather than motor or transformer circuits that would call for a C or D curve. Rated operational voltage is 230/400 V AC single-phase / multi-phase, with a maximum of 250 V single-phase and 440 V multi-phase. The 4.5 kA rating per EN 60898 means it safely interrupts fault currents up to that level under the standard's test conditions — adequate for most residential and light commercial service-entrance panels where the prospective short-circuit current stays within that limit. ## Mounting and integration Occupies a single modular width unit (18 mm) on standard DIN rail. Depth is 76 mm, installation depth 70 mm. Mounting position is unrestricted — any orientation works. The IP20 rating applies with conductors connected, which is the standard for enclosed distribution boards; the breaker itself is not rated for exposed wet-area installation without an enclosure. Touch protection is built in per product feature. The housing is halogen-free and silicon-free, which matters when specifying for environments sensitive to outgassing — clean rooms, certain medical or data-center adjacent spaces.","metaTitle":"Siemens 5SL3116-6MB SENTRON MCB, 1P B 16A 4.5kA","metaDescription":"Siemens SENTRON 5SL3116-6MB miniature circuit breaker, 1-pole, B-curve, 16 A, 4.5 kA per EN 60898.
