SDA3-10 Series

The SDA3-10 Solid State Contactor (SSR) is a high-performance DIN rail-mounted switching device designed for high-load applications up to 480VAC with 10A per phase capacity. This model supports a wide control voltage range of 4V32VDC or 90V250VAC, ensuring compatibility with various industrial control systems.

The zero-crossing switching technology minimizes inrush currents and reduces electromagnetic interference (EMI), enhancing the stability and lifespan of connected equipment. The integrated high-efficiency heatsink ensures optimal thermal dissipation for continuous and reliable operation. Additionally, the built-in LED control input indicator provides real-time status visibility. UL-certified, the SDA3-10 meets stringent safety and performance requirements, making it a trusted solution for industrial and commercial applications.
