The Siemens 5SL3240-7CC is a 2-pole miniature circuit breaker (MCB) rated 400 V with a 4.5 kA breaking capacity, C-trip curve, and 40 A current rating. It snaps onto a DIN rail in a distribution board or sub-panel, protecting downstream wiring and loads against overcurrent and short circuits. The C-curve (5–10× In) makes it suitable for inductive or motor-starting loads where inrush is moderate.
