It breaks 4.5 kA per EN 60898 and IEC 60947-2 at 400 V AC — enough for residential and light commercial distribution boards where the prospective fault current stays under that threshold. Rated for 50 Hz, multi-phase operation up to 440 V AC, and DC circuits up to 60 V. It occupies 3 width units (54 mm) on a DIN rail, mounts in any position, and accepts solid or stranded conductors from 0.75 to 35 mm². That's a wide wire range for a 10 A breaker — useful when you're feeding through a larger conductor for voltage drop or looping downstream.
Panel Fit & Wiring
Depth is 76 mm (installation depth 70 mm), height 90 mm, width 54 mm — three 18 mm width units. Sealable (yes) — you can lock the toggle position with a seal cap for tamper-proof isolation. Halogen-free and silicon-free construction, so no corrosive off-gassing in enclosed assemblies. Touch protection is built in on the line side.
Overvoltage category 3, energy limiting class 3. Suitability marked for residential buildings and infrastructure. Neutral conductor switching is not provided — this is a 3-pole breaker for 3-phase loads or line-only protection where the neutral is solidly bonded.
