The RZ3A60A75 is a 3-phase Solid State Relay with 3PST contacts, NORYL housing and nickel-plated copper base plate. This panel mount relay features zero crossing switching mode and screw terminals. Designed to switch various loads such as heating elements, motors and transformers. Built-in varistor secures transient protection. For higher reliability and load cycle capability three semiconductor power units are soldered directly on to the direct copper bonded (DCB) substrate.
