Eaton NSB DH221NGK Safety Switches

The Eaton NSB DH221NGK Safety Switch is a fusible, two-pole disconnect rated for 30 A at 240 V AC (50/60 Hz) in single-phase applications with a neutral. As part of Eaton's NSB family, it provides a clearly defined safety isolation point between the power source and downstream equipment, enabling a controlled de-energization sequence during maintenance, inspections, or fault conditions, while preventing inadvertent re-energization. The "fusible with neutral" designation means the device uses fuses to provide overcurrent protection and includes a neutral connection to satisfy loads that require a return path. With a 30 A, 240 V AC rating and 50/60 Hz compatibility for single-phase systems, the DH221NGK supports typical small- to medium-sized electrical installations that need a reliable, fuse-protected disconnect. The NSB DH221NGK is designed for industrial and commercial environments where safe isolation of 240 V circuits is essential for routine maintenance and equipment protection.
