The Siemens 5SL4106-7RC is a SENTRON miniature circuit breaker (MCB) — a single-pole, C-curve device rated 6 A with a 10 kA breaking capacity per EN 60898 at 240/415 V AC. This is the part you spec into a residential or light-commercial distribution board when you need a 1-module-width (18 mm) breaker that clears a 10 kA prospective fault current on a 240/415 V supply.
The 10 kA breaking capacity at 240/415 V AC (per EN 60898) is the headline number: it tells you this MCB can safely interrupt a fault current up to 10,000 A without welding its contacts or failing catastrophically. That covers most residential and light-commercial service entrances in Europe and markets using the 240/415 V three-phase system. The 6 A rating on a C-curve means it will hold steady at 6 A continuous and trip on overloads above roughly 30 A (5× In) to 60 A (10× In) — a good fit for protecting a 1.5 mm² lighting circuit or a small pump motor. Rated insulation voltage is 440 V AC for multi-phase operation and 250 V AC for single-phase, so this breaker can be used on a 230/400 V three-phase system as a single-pole branch protector. The 50/60 Hz frequency range covers standard mains supplies globally.
Physical integration and panel fit
At 18 mm wide (1 modular unit), 90 mm tall, and 76 mm deep, the 5SL4106-7RC snaps onto a standard DIN rail (EN 60715) and occupies a single slot in a consumer unit or distribution board. Mounting position is unrestricted — horizontal, vertical, or flat — which simplifies panel layout.
The 5SL4106-7RC carries an Active lifecycle status from Siemens. It is a current-production part in the SENTRON 5SL series, not subject to phase-out or last-time-buy. For a BOM that already qualifies this order code, there is no requalification trigger on the horizon.
