The GSD7666 is used for a wide range of applications, due to an
improved dynamic range allowing a basic current of 5 Amp while
retaining a maximum current of 80 Amp and extended functional
features. It is a compact and keypad-based design in a B58565
standard housing and maintains the rugged RF immunity withstand
of 30V/m and IP54 rating, allowing it to be installed in
harsh environments.
