Reliable replacement 40A Solid State Relay designed for infrared sauna control systems and other high-power switching applications. This SSR accepts a 3–32V DC control signal (including common 12V controllers) and can switch up to 40 amps at 24–480VAC, making it ideal for controlling sauna heaters and other resistive loads.

Commonly found in many infrared sauna brands such as Luxo & Komate Bio-Spectrum, this relay is a dependable replacement when your existing unit fails. Solid state design means silent operation, no mechanical contacts, and improved reliability compared with traditional relays.

Each relay also includes a syringe of thermal heat sink compound to ensure proper heat transfer when mounting to a heat sink or metal surface, helping extend the life of the relay.

Perfect for infrared sauna repairs, upgrades, and controller replacements.
