DH324NRK - 200 Amp Safety Switch

DH324NRK - 200 Amp Safety Switch

The Eaton DH324NRK is a 200-amp, 3-pole fusible safety switch with neutral designed for applications where equipment needs to be safely disconnected from power for maintenance, service, or inspection. Rated for 240 volts and housed in a NEMA 3R enclosure, it is commonly used in commercial buildings, industrial facilities, outdoor installations, and utility-related applications where a weather-resistant disconnect is required.

Its fusible design accepts Class H fuses, while the included neutral provision makes it suitable for applications that require a four-wire connection. The painted galvanized steel enclosure is intended for outdoor use and helps protect internal components from normal weather exposure. With support for copper or aluminum conductors ranging from #6 AWG to 250 kcmil, this switch can be used across a variety of commercial and industrial installations.

You'll commonly find the DH324NRK in manufacturing facilities, mechanical equipment areas, utility spaces, service entrances, and outdoor electrical systems where a properly rated disconnect is part of the installation. Built to last and designed for long-term use in compatible applications, it remains a practical choice for maintaining existing electrical infrastructure.
