The Solid State Contactor is capable of switching 1‑, 2‑, and 3‑phase applications with loads up to 63 A AC51 load and up to 24 A AC53a load. The Solid State Contactor is designed for DIN‑rail mounting with integrated heatsink and overvoltage protection. The heatsink is moved to the front for optimal convection cooling in the panel. Cable ducting system will not stop the airflow. The contactor elements are soldered directly on to the direct copper bonded sub‑strate (DCB‑technology). AC or DC controlled versions are available. Built‑in LED status indication for applied control voltage.
