Carlo Gavazzi RN1A48D30 Semiconductor Contactor

Carlo Gavazzi RN1A48D30 is a 1-pole solid-state contactor rated for 30 A at 480 VAC, designed to switch AC loads in automation circuits. It accepts a DC control input of 5–32 V, enabling direct interfacing with PLC outputs and other automation controllers. The device employs zero-cross switching on the output, which minimizes inrush and EMI when energizing resistive or moderate-inductive loads. The unit uses captive-clamp power connections and measures 45 mm in width, making it suitable for compact panel installations. Classified in the RN1A family, it sits in the 26–50 AAC current-rating category, reflecting its mid-range load capability while operating at a nominal 480 VAC line voltage. The RN1A48D30 is the specific model designation, and Carlo Gavazzi identifies a compatible procurement alternative with RGC1A60D30KKE for future sourcing. This solid-state contactor provides quiet, fast switching suitable for automation systems that require reliable control of higher-voltage AC circuits via low-voltage DC signals.
