The RM1A48D75 is a 1-pole, panel-mount solid-state relay from Carlo Gavazzi designed to switch AC loads with zero-cross switching, rated for 75 A at 42–530 VAC (1200 Vp). It accepts a DC control signal of 4–32 V (Uc) and includes built-in overvoltage protection, with screw terminals and captive clamps for secure wiring. The device supports AC-51 operation at 75 A and AC-53a up to 20 A, making it suitable for panel-mounted automation schemes that require reliable, quiet switching of mains loads in industrial control applications.
