Marinco Contour Chassis Battery Master Switch, 275A

The Marinco Contour Battery Master Switch controls your chassis battery with a simple turn, and its patented contour-lock design lets it stand alone or lock together with other Contour switches. The control knob can't be pulled off in the on or off position, but releases at a 45-degree anticlockwise turn.

Rated 275 amps continuous and 455 amps intermittent, it handles chassis loads with room to spare. Removable side plates on four sides give access for cables up to 1/0, and a rear cover insulates the terminals against short circuits. Includes a chassis label.
