Mounting Quick install rail mounting EN 50022-35, width:35 mm (1.38 in.)
Weight 210 g (0.46 lb.)
NOTE 1: Install arc
suppressor devices across
load to avoid module
contact arcing and ensure
specified relay life
expectancy.
NOTE 2: Total operations =
operations at power factor 1
multiplied by the limitation
factor. If the power factor is
0.5 at 230 Vac, 2A
(1,000,000
operations), the
limitation factor is 0.70.
1,000,000 x 0.70 = 700,000
total operations.
