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.
Physical fit and environment
Width is 36 mm (2 modular units), depth 76 mm. Mounts on standard DIN rail in any position—vertical, horizontal, upside-down if the cabinet forces it. 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.
