The Siemens 5SL6563-7CC is a 1+N-pole miniature circuit breaker rated 63 A with a C-trip curve, breaking capacity of 6 kA at 230 V. It's a current-production Basic Device from the 5SL6 family, meaning it's still a standard catalog line — no last-time-buy scramble needed for this one.
At 63 A it's sized for a main incomer in a small sub-distribution board or a heavy feeder. The 1+N-pole configuration switches both line and neutral, with overcurrent protection on the line pole only. That's typical for single-phase final circuits where you want the neutral switched for isolation but don't need a double-pole thermal element.
Sourcing and fit
This is a standard DIN-rail mount MCB — snaps onto a 35 mm rail, occupies two modular spaces (1+N). The 63 A rating and C-curve are printed on the front face, so a quick visual check confirms the BOM match.
