Product details

MCB for railway and industrial panels

Designed specifically for railway applications, it also suits general mechanical engineering and industry use.

B-curve means magnetic trip between 3 and 5 times In — 18 to 30 A for this 6 A unit. The 35 kA breaking capacity under IEC 60947-2 is the rating that matters for industrial coordination studies; the 10 kA EN 60898 figure is the domestic/commercial limit. At 40 °C ambient the continuous current derates to 5.63 A; at 60 °C it drops to 4.82 A — factor that into your load schedule if the panel runs hot.

Frequently asked questions

Where can I buy 5SY4206-6KK11 and how do I get a price?

This part is sourced and quoted to order against an RFQ through our independent distribution channel. Submit an RFQ for current pricing and availability — no stock or price figures are published here.

What is the breaking capacity of 5SY4206-6KK11?

10 kA per EN 60898 and 35 kA per IEC 60947-2. The IEC 60947-2 figure is the one used for industrial coordination studies.

Will 5SY4206-6KK11 drop into a panel specified around 5SY7210-7CC?

Both are 2-pole SENTRON MCBs on the same DIN-rail footprint, so the mechanical fit is the same. The key difference is the rating: 5SY4206-6KK11 is 6 A B-curve; 5SY7210-7CC is a different current/curve combination. Verify the load current and coordination study before swapping.
