1
Electromechanical relays warranted for 100,000 closures only. Solid-state switching devices recom-
mended for applications requiring fast cycle times or extended service life.
2
To effect IP65/NEMA 4X rating requires a minimum mounting panel thickness of 1.5 mm (0.06 inch)
and surface finish not rougher than 812µ mm (0.32µ inch).
3
Switching inductive loads (relay coils, etc.) requires using an RC suppressor.
