The Siemens SENTRON 5SY6613-6 is a 4-pole miniature circuit breaker (3P+N) with a B-curve trip characteristic, rated 13 A at 50/60 Hz AC. It is designed for branch-circuit overcurrent and short-circuit protection in industrial control panels, distribution boards, and mechanical-engineering installations.
The 13 A rating holds at 35 °C; derate to 12.48 A at 40 °C, 12.22 A at 45 °C, 11.95 A at 50 °C, and 11.67 A at 55 °C — plan your continuous load against the ambient temperature of the enclosure. The higher IEC figure applies when the breaker is used in industrial distribution with a known upstream fault level; the EN figure governs in residential or light-commercial boards. Mounts in any position via the quick-assembly system — snaps onto standard DIN rail.
Halogen-free and silicon-free construction reduces corrosive off-gassing in enclosed panels. Sealable for lockout/tagout. Ambient temperature range -40 to 75 °C with humidity limits per.
