The CARLO GAVAZZI RZ3A series is a family of solid-state relays engineered for robust industrial applications such as switching heating elements, motors, and transformers. These relays offer high voltage switching capabilities up to 600 VACrms, with a built-in varistor for enhanced transient protection. The DCB substrate and available AC or DC control versions ensure reliable operation and extended load cycle capability. Featuring LED status indication for control voltage and over-temperature alarm (optional), the RZ3A series covers a range of load currents up to 75 AACrms, making it suitable for plastic extrusion machines, coffee machines, and other demanding industrial equipment.
