Production status and compliance
The 5SY4220-5: It carries approvals to IEC/EN 60898-1, IEC/EN 60947-2, and UL1077. That trio covers most of the world—CE mark territory, panel shop specs in North America, and machine builders who cite IEC standards. The halogen-free and silicon-free construction simplifies disposal compliance and avoids outgassing in sensitive enclosures.
Width is 36 mm (2 modular units), depth 76 mm. Quick-assembly system clips it on without tools. Temperature range from -40 to 75 °C, with IP20 protection when conductors are connected. Vibration-rated to 50 m/s² from 25 to 150 Hz—will it survive the route? Yes, if the panel is bolted down. Pollution degree 3 covers factory-floor dust and conductive deposits.
