The G3PE515B3NDC1224 is a compact, three-phase solid state relay with an integrated heat sink, designed for controlling heater loads. It operates with a 12 to 24 VDC input and is rated to switch a 15 A resistive load at a voltage of 200 to 480 VAC. This DIN rail mountable SSR features phototriac coupler insulation, a zero-cross function to minimize switching noise, and a yellow LED operation indicator. Its slim profile and surge pass protection make it suitable for industrial heating applications where reliable switching and space efficiency are critical.
