Sourcing note: current-production 4-pole D-curve MCB
The 5SY4410-8: The enclosure seals (IP20 with connected conductors) and carries overvoltage category III with pollution degree 3, so it suits industrial control panels where transient overvoltages are expected, not just residential distribution. Halogen-free and silicon-free construction — relevant if the panel sits in a clean-room or process area where halogens could attack sensitive contacts or optics.
Mounting and integration
Occupies 4 modular width units (72 mm) on the DIN rail. Overall body measures 90 mm tall, 76 mm deep; installation depth is 70 mm with the quick-assembly system. Accepts supply from either end — any position — and the combined top/bottom terminals simplify daisy-chaining in multi-pole assemblies. The neutral conductor is not switched — onboard neutral bar required for 4-pole applications where the neutral must be opened. Mounting position any; vibration resistance tested per IEC 60068-2-6 to ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz.
Lifecycle and sourcing
Listed as current production (lifecycle stage: current) — no phase-out notice or last-time-buy applies to this order code. Sourced to order against an RFQ; typical lead time varies with batch size and current factory load, so quote to confirm delivery.
