The Siemens SENTRON 5SY4205-7CC11 is a 2-pole miniature circuit breaker (MCB) with a C-curve trip characteristic, rated 0.5 A at 50/60 Hz. Its 10 kA breaking capacity per EN 60898 means it can safely interrupt fault currents up to that level in a 230/400 V AC circuit — enough for most sub-distribution boards in industrial or railway auxiliary panels.
Width is 36 mm (2 modular units), depth 76 mm, height 90 mm.
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 date and price.
10 kA per EN 60898 at 50/60 Hz, which is the standard for this class of MCB in sub-distribution.
Both are 2-module-wide (36 mm) SENTRON MCBs with the same DIN-rail footprint and terminal arrangement, so physical swap is straightforward. The difference is the rating: 5SY4205-7CC11 is a 0.5 A C-curve, while the 5SY4140-7 is a different current. Verify the load draw before substituting — the mechanical fit is identical.
