Product Description
The zero switching relay with
antiparallel thyristor output is
the most widely used indus-
trial SSR due to its multiple
application possibilities. The
relay can be used for resis-
tive, inductive and capacitive
loads. The zero switching
relay switches ON when the
sinusoidal curve crosses zero

built-in varistor secure transi-
ent protection for the heavy
industrial applications and

cover is securing touch pro-
tection.
