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. Capable of handling high voltages up to 690 VACrms, the RZ3A60D75 model offers zero switching functionality and a broad control voltage range (4-32 VDC or 24-275 VAC). The integrated varistor provides crucial transient protection, while the DCB substrate enhances reliability and cycle capability. Available with optional over-temperature protection and alarm output, this relay is ideal for plastic extrusion machines, coffee machines, and other demanding industrial environments.
