For North American installations, it carries a 5 kA rating per UL 1077 and CSA C22.2 No. 235 — enough for supplementary protection in a control panel fed from a larger upstream device. The 36 mm width (2 width units) and 76 mm depth let it drop into standard DIN-rail enclosures without surprises. It mounts on a quick-assembly system, accepts any mounting position, and the terminals are combined top and bottom — no reorienting the busbar when you land the load side.
For BOM compliance, the 5SY4216-6CC carries UL, CSA, and CE marks. It's halogen-free and silicon-free, which matters in clean-room or high-reliability environments where outgassing can contaminate contacts or optics.
Deployment context
That covers outdoor cabinets in cold climates and hot machine compartments near ovens or hydraulics.
