This is a 4-pole main switch designed for direct current isolation within control panels. It functions as an isolator, disconnecting all poles simultaneously to enable safe de-energisation of DC circuits. Typical applications include power distribution sections of industrial panels where DC supply must be isolated for maintenance or safety purposes.
