Original OMRON G3NA-210B-UTU Solid State Relay (SSR)
The OMRON G3NA-210B-UTU Solid State Relay (SSR) is needed for safety shutoff of the 230V bed heater in your 3D printer. To make sure your bed heater shuts off in case of a thermal runaway event, a SSR in combination with a bed thermistor disconnects the power to the heater in case of an overtemperature event occurring. These SSRs are genuine, sourced from an official distributor (be careful, there are many fake ones on the market, especially on ebay).
