At 40 °C ambient the continuous rating derates to 36.88 A, so a panel running warm needs to account for that headroom. ## Deployment context Mounting position is unrestricted, so it can go sideways or upside-down in a tight cabinet without derating the thermal trip.","metaTitle":"Siemens 5SL6140-8CC SENTRON MCB, 1P D 40A 6kA","metaDescription":"Siemens SENTRON 5SL6140-8CC miniature circuit breaker, 1-pole, D-curve, 40 A rated, 6 kA breaking capacity per EN 60898.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time."},{"question":"Will 5SL6140-8CC drop into a panel specified around 5SL6132-6MB?","answer":"Both are 1-pole SENTRON MCBs on the same DIN-rail footprint (18 mm width per modular unit), so the mechanical fit is identical. The difference is the rating: 5SL6140-8CC is a 40 A D-curve, while 5SL6132-6MB is a different rating and characteristic — verify the load's inrush and continuous current before swapping without rewiring the distribution board."},{"question":"What compliance documentation does Siemens provide for 5SL6140-8CC?","answer":"The breaker carries IEC 60898 certification for the 6 kA breaking capacity. It is halogen-free and silicon-free, rated for overvoltage category III and pollution degree 2. Touch protection is integrated on the terminals.
