Weight 220 g (0.49 lb.)
NOTE 1: Install arc suppressors across load to avoid module contact
arcing and ensure specified contact 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 (750,000
operations), the limitation factor is 0.70. 750,000 x 0.70 = 525,000 total
operations.

CONTACT DAMAGE
To ensure the 1 mA capability
during the lifetime of the
contact, NEVER exceed 300
mA or 60 V.
Failure to comply with these
instructions will result in
loss of low current
switching capability.
