The Siemens 5SL6201-7CC is a SENTRON miniature circuit breaker — 2-pole, C tripping characteristic, rated 1 A at 400 V AC with a 6 kA breaking capacity per EN 60898.
Thermal derating — the real-world rating
At 40 °C it derates to 0.92 A; at 50 °C to 0.84 A; at 55 °C to 0.79 A. The 1 A rating is only valid at 30 °C.
Mounting and environment
Snaps onto a DIN rail, any mounting position. IP20 with conductors connected — fine inside a closed panel, not for wet locations. Halogen-free and silicon-free construction, which matters for clean-room or semiconductor-fab installs where outgassing is a concern.
