Eaton DH221NDK Heavy Duty Safety Switch Disconnect

Product Description

The EATON DH221NDK is a heavy duty safety switch designed for industrial and commercial electrical distribution systems. Safety switches in this class serve as disconnect means for motors, HVAC equipment, and other load types, providing a visible, lockable point of isolation that meets NEC requirements for service and maintenance disconnects. Licensed electricians install this type of device during new construction or retrofits where a code-compliant disconnect is required ahead of a load.

Heavy duty safety switches like the DH221NDK are commonly specified in commercial buildings, light industrial facilities, and mechanical rooms. They are used ahead of compressors, air handling units, pumps, and similar equipment where a robust, durable disconnect is required and where the device may see regular use or harsh environmental exposure.
