Carlo Gavazzi RZ3A: Solid State Relays, 3 Phase, Zero Switching

The RZ3A line is a 3 phase, zero switching 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 over-temperature alarm (optional). A version that can be controlled with 5 VDC @ 15 mA (max) is also available (LD). The series covers a range of load currents up to 75 AACrms.
