Eaton DH421FGK Fusible Disconnect Switch NEMA 1

Eaton DH421FGK Fusible Disconnect Switch is a 30 A, 240 V, four-pole, four-wire disconnect designed for indoor installation in a NEMA 1 enclosure. It accepts Class H fuses and is described as heavy duty, providing a safe, accessible means to isolate power for circuits that require fusible protection. As a fusible disconnect, it combines a protective fuse element with a switch to permit safe power interruption at the point of service, making it a straightforward solution for electrical distribution where Class H fuse protection is specified. The 4P 4W configuration supports multi-line connections in a compact package, while the NEMA 1 enclosure configuration indicates indoor, non-weatherproof service. Built to Eaton’s standards, this model offers consistent performance for applications needing a reliable, fusible isolation switch with a clear on/off mechanism and fuse protection.
