Siemens 5SL1106-7MB SENTRON MCB – 1-pole, C-curve, 6 A
The Siemens 5SL1106-7MB is a SENTRON miniature circuit breaker (MCB) with a single pole, C-trip characteristic, and a 6 A rated current. It breaks fault currents up to 3 kA per IEC 60947-2 at 230/400 V AC, 50/60 Hz. That 3 kA rating means it is sized for residential and light commercial sub-distribution where the prospective short-circuit current stays under that threshold — not for high-fault industrial mains where a 10 kA or higher unit would be required. The C-curve (5–10× In) handles moderate inrush from small motors, transformers, or capacitive loads without nuisance tripping. Occupying a single modular width unit (18 mm) on a DIN rail, it snaps into standard distribution boards. The IP20 rating (with connected conductors) is typical for enclosed panel use — no washdown or outdoor exposure. Halogen-free and silicon-free construction matters for installations where off-gassing or silicone contamination must be avoided, such as in clean rooms or sealed enclosures.
Integration notes
Mounts in any position on a standard DIN rail. The 76 mm depth and 70 mm installation depth fit typical consumer-unit and sub-distribution enclosures. The sealable design allows the installer to lock the toggle position after commissioning — useful for tamper-proofing in shared or public-access panels. Overvoltage category III and pollution degree 2 align with fixed-installation requirements per IEC 60947-2.
