Integrator's note — 5SL6505-7BB
The Siemens 5SL6505-7BB is a SENTRON 5SL6 miniature circuit breaker, 1P+N, rated 0.5 A at 230 V AC with a C tripping characteristic and 6 kA breaking capacity per EN 60898 and IEC 60947-2.
The 0.5 A rated current is the continuous load the breaker carries without tripping — sized for low-current lighting or control circuits, not motor or general-purpose power. The 1P+N configuration (2 poles, one switched neutral) is common in single-phase distribution where the neutral is switched for isolation but not protected against overcurrent.
Panel integration
Accepts solid or stranded conductors from 0.75 to 25 mm²; tighten screw terminals to 2.5–3 N·m. The sealable cover allows panel builders to lock settings after commissioning. Halogen-free and silicon-free construction avoids corrosive off-gassing in enclosed assemblies. Ambient operating range -25 to +45 °C, storage -40 to +75 °C.
