This Carlo Gavazzi RA4425LA08 is a panel‑mount solid state relay designed for reliable switching of AC loads in industrial control systems. It offers a rated operational current of 25 A with a load voltage range of 42–480 VAC, making it suitable for heaters, motors, and other high‑duty single‑phase loads. The relay features zero‑cross switching for reduced electrical noise and direct copper bonding technology for improved thermal performance and long service life. With a wide control input of 10–90 VAC/VDC, it can interface easily with many control systems and PLC outputs.
Load voltage (operating): 42–480 VAC (up to about 400–440 VAC typical applications)
Rated load current: 25 A AC at 40–50 °C ambient
Control/input voltage: 10–90 VAC or 10–90 VDC
Switching mode: Zero‑cross (ZS) for low EMI and reduced inrush stress
Insulation: Up to 4 kV, suitable for industrial environments
Mounting: Panel mount with screw terminals and metal baseplate for heatsink or panel
Industrial automation and machine control upgrades or maintenance
Heating elements, ovens, and resistive or moderately inductive loads
Hobbyists and small companies needing a robust, brand‑name SSR for prototypes or retrofits
