The Siemens 5SY6115-8CC is a 1-pole SENTRON miniature circuit breaker rated 1.6 A at 400 V AC with a D tripping characteristic. Overvoltage category III means it's rated for fixed-installation distribution panels, not just downstream equipment.
The 1-pole body takes 76 mm depth behind the panel, with 70 mm installation depth. Torque to 2.5–3.5 N·m. IP20 with conductors connected, so it's panel-internal only — no washdown exposure.
6 kA per EN 60898 at 400 V AC, and 5 kA per UL 1077 / CSA C22.2 No. 235. The EN rating governs European distribution panels; the UL figure matters for North American installations where the MCB is used as a supplementary protector.
Solid or stranded conductors from 0.75 mm² up to 35 mm². The combined top and bottom screw terminals accept the full range; torque to 2.5–3.5 N·m.
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 position.
Both are 1-pole SENTRON MCBs on the same 18 mm DIN-rail footprint with identical terminal ranges, so the mechanical swap is direct. The difference is rating: 5SY6115-8CC is 1.6 A D-curve, while 5SY6140-6CC is a higher-current variant with a different characteristic. Verify the load current and trip curve match your circuit before substituting.
