1 Electromechanical relays warranted for 100,000 closures only.
Solid-state switching devices recommended for applications
requiring fast cycle times or extended service life.
2 Switching inductive loads (relay coils, etc.) requires using an RC
suppressor.
3 Operating environment is 0 to 60°C for line voltage exceeding 240V.
4 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 812
µ
mm (0.32
µ
inch). Use Greenlee punch 60287.
