If it's not locked, it's not safe. Overvoltage category III confirms it can handle distribution-level transients on the line side. ## Mounting and enclosure fit Depth is 76 mm, width 72 mm, height 90 mm — 4 modular width units (4 M). Mounting position any, fastening is via the quick assembly system (standard DIN rail). Installation depth 70 mm; vibration resistance tested to ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz. ## Breaking capacity — match your SCCR Breaking capacities: 10 kA, 35 kA AC, 15 kA DC, 5 kA (UL/CSA). Verify system SCCR does not exceed the applicable rating. Supply frequency 50/60 Hz; rated voltage 400 V AC (440 V multi-phase).","metaTitle":"Siemens 5SY4402-5 SENTRON MCB, 4P, 2A, Char.
