Carlo Gavazzi RGC1A60A25KKE is a single-pole DIN-rail solid-state relay in the E-layout format with integrated heatsink, rated for an operating voltage of 42-660 V AC (1200 V peak) and a load current of 25 A AC (AC-51). Switching is at zero-crossing and the control input accepts 20-275 V AC or 21.6-190 V DC, with built-in overvoltage protection. Screw terminals with captive clamp accept the power connections. Typical use is control-panel switching of heaters, transformers and other resistive or lightly inductive loads.
