Product details

The Siemens SENTRON 5SY5108-6 is a 1-pole miniature circuit breaker with a B tripping characteristic, rated 8 A at 35 °C and breaking 10 kA per IEC 60898.

At 40 °C the breaker derates to 7.62 A, at 50 °C to 7.22 A, and at 60 °C to 6.78 A; if the panel ambient runs hot, factor the thermal derating into the branch-circuit design. The 10 kA breaking capacity at 230/400 V AC (per IEC 60898) and 10 kA at 220 V DC (per EN 60898-2) means it can safely clear a fault up to that level without upstream damage.

Mounting and integration notes

Snap-on DIN rail mounting, any orientation. The sealable design allows lockout/tagout. Halogen-free and silicon-free construction meets clean-room and high-reliability plant specs. IP20 with connected conductors — keep the panel enclosure closed during washdown.
