The G3NA/G3NE SSR products are a great fit for commercial in-line toasters and food heating applications, such as toasting submarine sandwiches at Quizno's and the breakfast sandwiches at McDonald's. By extension, these SSRs are clearly a good fit for switching any large current/resistive loads that cycle on/off regularly and for similar equipment that is on for extended periods. If heat build-up and high ambient temperature are issues, models are available with optional heat sinks.
