Product details

Ratings that matter for fit

If your panel was laid out for a 5SL4363-7 (which is a 3-pole unit with similar breaking capacity), the 2-pole 5SY6210-7 won't swap in without rewiring the neutral path: this breaker does not switch the neutral conductor, so it's for line-side protection only. For a 2-pole application, though, the footprint and DIN-rail clip are identical, and the 15 kA IEC rating matches the 5SL's high-fault capability.

Mounting and environment

Mounts in any position, quick-assembly system on DIN rail. Depth is 76 mm (70 mm installation depth), width 36 mm — two modular units. IP20 with conductors connected, pollution degree 3, overvoltage category III.
