Product De scrip tion

The zero switching relay with
triac (10 A) or thyristor output
(25 A, 40 A) offer a solution
for resistive load switching.
The zero switching relay
switches ON when the sinus­oidal voltage 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 to IP 20. Output ter­minals can handle cables up
to 16 mm2.
