Frequently asked questions
What are the key ratings for 5SY5202-7CC12?
2-pole DC miniature circuit breaker, 2 A at 35 °C, C characteristic, rated 440 V DC (max 500 V DC), 10 kA breaking capacity. Designed for railway applications per EN 61346-2 type F.
Where can I buy 5SY5202-7CC12 and what is the price?
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 5SY5202-7CC12 fit a panel designed for a 5SY5250-7?
Both are 2-pole SENTRON 5SY5 series MCBs with the same 36 mm width (2 MW) and DIN-rail mounting. The 5SY5202-7CC12 is a 2 A C-curve DC railway type; the 5SY5250-7 is a higher-current variant. They share the same footprint and terminal layout — no rewiring needed for the swap, but verify the current rating and DC application match your circuit.
What compliance documentation does Siemens provide for 5SY5202-7CC12?
The part is halogen-free and silicon-free. As a Siemens SENTRON railway-series MCB, it carries CE marking and is designed to IEC/EN 60898 and IEC/EN 60947-2 standards. RoHS and REACH declarations are available from Siemens documentation for this product family.
