RZ3A 3-Phase ZS Solid State Relay
A Solid State Relay family designed to switch various loads such as heating elements, motors and transformers.
The relay is capable of switching high voltages up to 600 VACrms. The built-in varistor secures transient protection for heavy industrial applications.
For higher reliability and load cycle capability three semiconductor power units are soldered directly on to the direct copper bonded (DCB) substrate. AC- or DC-controlled versions are available. Built-in LED status indication for applied control voltage and overtemperature alarm (optional).
The series covers a range of load currents up to 75 AACrms.
