Product details

The Siemens SENTRON 5SL6140-8CC is a 1-pole miniature circuit breaker with a D tripping characteristic, rated 40 A at 30 °C and 230/400 V AC. 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.

Frequently asked questions

What is the breaking capacity of 5SL6140-8CC?

The breaking capacity is 6 kA per EN 60898 at 230/400 V AC, which is the standard rating for residential and light commercial distribution boards.

Where can I buy 5SL6140-8CC and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

Will 5SL6140-8CC drop into a panel specified around 5SL6132-6MB?

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.

What compliance documentation does Siemens provide for 5SL6140-8CC?

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. Full RoHS and REACH declarations are available from Siemens on request.
