The RJ1A series are a single‑phase Solid‑State Contactor designed to replace electro‑mechanical contractors in industrial heating and motor applications, especially when switching is frequent. The product is ready to mount on DIN‑rail or chassis and comes with integral heatsink. The standard housing dimensions enable installation in limited space and the terminal layout allows both contactor (E) and SSR (U) type connection. Two 2.5mm2 cables can be connected in each screw terminal to allow looping. A removable IP20 cover allows connection of a 4mm2 cable with crimped terminal.
