The Siemens 5SY4605-8CC11 is a 4-pole (3P+N) miniature circuit breaker from the SENTRON series, designed for 400 V AC systems with a D tripping curve and a 0.5 A rated current. Rated 400 V AC phase-to-phase, 440 V AC multi-phase, max 72 V DC. 4 width units (72 mm wide).
Current-production Siemens SENTRON MCB.
Solid and stranded conductors from 0.75 mm² up to 35 mm². The combined box terminals at top and bottom handle both fine-stranded and solid wire.
Both are 4-pole SENTRON MCBs on the same DIN-rail footprint, but the 5SY4605-8CC11 is a D-curve 0.5 A device while the 5SY7140-8CC is a different rating and characteristic. Verify the tripping curve and ampacity match your branch circuit before substituting — the mechanical fit is the same, but the protection coordination may differ.
