SENTRON 5SY4605-8 — D-curve 0.5 A MCB, 4-pole
The Siemens 5SY4605-8 is a SENTRON-series miniature circuit breaker with a D tripping characteristic, rated 0.5 A at AC, across 4 poles configured as 3P+N.
Breaking capacity and derating
Rated breaking capacity is 10 kA per EN 60898 and 35 kA per IEC 60947-2 at AC; at DC the IEC 60947-2 rating drops to 15 kA. Those numbers govern where this breaker can be installed — the 10 kA EN rating covers standard domestic/commercial distribution, while the 35 kA IEC rating qualifies it for industrial panel applications with higher prospective fault current. Temperature derating is published: at 40 °C the 0.5 A rating holds at 0.48 A, at 50 °C it's 0.45 A, at 60 °C it's 0.42 A.
Panel integration
Combined terminals top and bottom; touch protection is included. Sealable for lockout/tagout compliance.
