The D-curve (10–20× In) is the key spec here — it avoids nuisance tripping on motor starts, transformer inrush, or capacitive loads where a B- or C-curve would drop out. That makes it a fit for motor branch circuits, small drives, and industrial control panels where the load draws a heavy startup current. At 30 °C ambient the breaker holds a full 6 A; at 40 °C it derates to 5.68 A, and at 55 °C to 5.17 A. Snap-on DIN rail mounting, any position accepted. That dual rating means the same part satisfies residential distribution board specs and light industrial panel SCCR requirements. Energy limitation class 3 keeps the let-through energy low enough for most downstream equipment to survive a fault without cascading damage. Not designed for frequent switching duty like a contactor or motor starter; use it for overcurrent protection, not as a load-break switch.","metaTitle":"Siemens 5SL4206-8 SENTRON MCB, 2-pole D 6A, 10 kA","metaDescription":"Siemens 5SL4206-8 SENTRON miniature circuit breaker, 2-pole, D-curve, 6 A rated, 10 kA breaking capacity at 400 V AC.
