Product Description
Ordering Key
RZ 3 A 60 D 75 P
A Solid State Relay family designed to switch various loads such as heating ele- ments, motors and transform- ers. The relay is capable of switching high voltages up to
600 VACrms. The built-in varistor secures transient pro- tection for heavy industrial applications.
For higher reliability and load cycle capability three semi-
Type Selection
conductor power units are sol- dered directly on to the direct copper bonded (DCB) sub- strate. AC- or DC-controlled versions are available. Built-in LED status indication for ap- plied control voltage and over- temperature alarm (optional).
The series covers a range of load currents up to 75
