Carlo Gavazzi Electromatic RZ4040HAU1 Relay is a three-phase solid-state relay (SSR) in the RZ family, rated for 400 VAC and 40 A. As part of Carlo Gavazzi's Electromatic line, it switches AC loads using solid-state electronics rather than mechanical contacts. The model name indicates a maximum load voltage of 400 VAC and a continuous load current rating of 40 A, making it suitable for three-phase AC switching in industrial automation applications where reliable, maintenance-free control of higher-power loads is required.
