Product De scrip tion
The zero switching relay is an
inexpensive solution for
resistive loads. The zero
switching relay switches ON
when the sinusoidal curve
crosses zero and switches
OFF when the current crosses zero. The LED indicates
the status of the control
input. The clip-on cover is
securing touch protection (IP
20). Output terminals can
handle cables up to 16 mm
