The built- Switching mode used indus trial SSR due in varistor secures transient Rated operational voltage to its multiple application protection for the heavy Control voltage possibilities. The relay industrial applications, and Rated operational current can be used for resistive, the LED indicates the status inductive and capacitive of the control input. The loads. The zero switching clip-on cover is securing relay switches ON when the touch protection to IP 20. sinusoidal curve crosses zero Protected output terminals and switches OFF when the can handle cables up to 2 current crosses zero. 16mm .
