Schneider Electric's Square D 8430DIA4V19 is an AC/DC current control relay from the 8430 family, designed to sense and switch loads within control circuits in industrial equipment. The DIA4V19 variant specifies a 110 VAC coil and a load-switching range of 0.5–5 A at 50/60 Hz, making it suitable for moderate-current control tasks in automation panels. This relay is part of Square D's legacy relay line and is commonly used in motor-control and process-control applications where compact, reliable current control is required.
