Rated for a 50 A branch — B-curve, 6 kA, 400 V AC
The 50 A rating handles feeder or sub-feeder protection in distribution boards, control panels, and machinery enclosures.
Mounting and integration — 1 width unit, quick-assembly, any position
Occupies 1 width unit (18 mm), depth 76 mm, height 90 mm. The installation depth is 70 mm. Any mounting position is permitted. The combined top and bottom terminals accept solid or stranded conductors from 0.75 to 35 mm²; tighten screw terminals to 2.5–3.5 N·m. Sealable (yes) for tamper-proof isolation.
Environmental and compliance — halogen-free, silicon-free, wide temperature range
Halogen-free and silicon-free construction suits sensitive environments — clean rooms, electronics assembly, or areas where outgassing must be minimized. Humidity tolerance: max 95% at 55 °C, derating at higher temperatures. Overvoltage category III. Energy limiting class 3. The 5SY series carries the 5SY6CC design variant for this specific rating.
