Carlo Gavazzi RN1A48A10U Semiconductor Contactor

Carlo Gavazzi RN1A48A10U Semiconductor Contactor is a compact solid‑state switch designed to reliably drive AC loads in automation panels. It is rated for 400/480 VAC on the load side and accepts a control input of 24–265 VAC or DC, enabling flexible wiring schemes. The device handles up to 10 A of load current and uses zero‑cross switching with built‑in overvoltage protection for smoother operation in variable mains environments. Contactor elements are mounted on ceramic with insulation to the heatsink exceeding 4000 V, and the heatsink is integrated on the back to save panel space. The enclosure measures 80 × 22.5 × 100 mm and supports DIN‑rail or backplate mounting with a standard SSR-style terminal layout. It carries CE marking, confirming compliance with relevant safety standards. Typical applications include switching resistive and inductive AC loads in control panels, such as heaters, pumps, and laboratory/test equipment, where fast, repeatable switching and long life are essential.
