Cutler-Hammer DR3040UW Rotary Disconnect Switch

The Cutler-Hammer DR3040UW is a rotary disconnect switch engineered specifically for isolating fixed electrical circuits in industrial environments requiring durable manual control. Operating under 600 Volts at 60Hz with a continuous current capability of 40 Amps, this switch manages standard branch feeder loads while maintaining a robust safety barrier. Its Type 4X rated enclosure offers comprehensive protection against environmental factors including windblown dust, rain, sleet, snow, and hose-directed water, while also accommodating corrosive conditions found in outdoor or washdown zones. When the handle rotates, it mechanically opens the contacts to create a physical separation in the power path, allowing authorized personnel to verify a dead line for maintenance tasks or lockout procedures according to workplace safety regulations.
