Breaking capacity hits 25 kA per IEC 60947-2 and 5 kA per UL 1077/CSA C22.2 No. 235, so it handles substantial fault current in industrial panels. Mounts on a 36 mm wide DIN rail (2 width units) via the quick-assembly system; any mounting position is acceptable. The 76 mm depth leaves room in shallow enclosures, and the 70 mm installation depth matches standard SENTRON comb-busbar grids. Touch protection is integrated, and the sealable design allows lockout-tagout compliance on the panel door.
The halogen-free and silicon-free construction supports clean-room and sensitive electronics environments.
Peer comparison: 5SY7140-8CC
The closest functional peer is the 5SY7140-8CC, which shares the same D-curve, 2-pole form factor, and SENTRON 5SY7CC design. The difference is rated current: 10 A on the 5SY7210-8CC versus 14 A on the 5SY7140-8CC. Both carry 25 kA IEC breaking capacity. If a panel was specified around the 5SY7140-8CC, swapping to the 5SY7210-8CC requires verifying the load current does not exceed 10 A — the footprint and busbar pitch are identical, so no rewiring is needed beyond the ampacity check.
