The Carlo Gavazzi RJ1A / RJ1B Solitron series of single-phase solid state contactors is designed to replace electro-mechanical contactors in industrial heating and motor applications, especially when switching is frequent. The Carlo Gavazzi RJ1A / RJ1B Solitron Solid State Relay is ready to mount on DIN-rail or chassis and comes with integral heatsink. For current ratings of 75AACrms or 90AACrms (depending on model), convection cooling is achieved with the aid of an integrated fan for over-temperature protection. The Carlo Gavazzi RJ1A / RJ1B Solitron Solid State Relay's standard housing dimensions enable straightforward replacement of alternative products, and the terminal layout allows both contactor (E) and SSR (U) type connection.

The Carlo Gavazzi RJ1A / RJ1B Solitron Solid State Relay features an LED to indicate the status of the control input. The superior heat-transfer efficiency combined with a robust power management system make the The Carlo Gavazzi RJ1A / RJ1B Solitron Solid State Relay a highly reliability products that can meet the most stringent functional requirements.
