Eaton DD368NDKW-00V1 fused safety switch - UL Listed
Part Number: DD368NDKW-00V1
Quick Summary
Eaton DD368NDKW-00V1 fused safety switch provides reliable isolation for large electrical feeders in industrial facilities. Many sites struggle with downtime when switches lack a neutral path or fail to indicate line voltage during maintenance. UL Listed certification and a rugged NEMA 12/3R enclosure help resist dust, moisture, and harsh service conditions on the plant floor. With a fusible configuration that includes neutral and a voltage indicator on the line side, it simplifies wiring, improves safety, and supports motor and process protection. This combination also aligns with common industrial controls architectures, reducing project risk and accelerating commissioning. Designed for heavy-duty usage, it scales from plant floor feeder lines to distribution panels, delivering predictable performance across shifts.
