Its interrupting capacity is 15 kA at 230/400 V AC, which means it can safely clear a fault current up to that level without rupturing — essential for high-fault installations like sub-distribution boards near large transformers. Snaps onto standard DIN rail inside a panel or distribution board. The 1P+N form factor occupies one width module plus the neutral pole, so it fits a compact single-phase final sub-circuit. The D-curve (D0.5) means the magnetic trip threshold is 10–20× In, suited for loads with high inrush — think small transformers, solenoid banks, or control circuit supplies where a B-curve would nuisance-trip. Rated 0.5 A continuous — verify the downstream cable and load don't exceed that.","metaTitle":"Siemens 5SY4505-8CV MCB, 1P+N D0.5, 15kA Icu 230/400V","metaDescription":"Siemens 5SY4505-8CV miniature circuit breaker, 1P+N, D0.5A, 15kA Icu at 230/400V AC.
