Eaton DH466FGK Heavy duty fusible safety switch - UL Listed
Part Number: DH466FGK
Quick Summary
Eaton DH466FGK heavy duty fusible safety switch provides safe isolation for 3‑phase motor circuits in industrial control panels. In the field, uptime suffers when protection enclosures are hard to access, wiring configurations are scattered, or maintenance requires invasive work. This UL Listed device uses a NEMA 1 painted steel enclosure and Class H fuse provision to deliver reliable protection in interior environments, while supporting up to 600 V and 600 A. With its robust construction, it pairs well with standard control gear and provides clear compatibility for panel builders and OEMs seeking durable, compliant motor protection that scales with line current and HP ratings.

Heavy Duty, Fusible without neutral
High-current protection for large motors helps minimize fault energy and protects critical drive trains. The DH466FGK is rated for up to 600 A and supports 400–500 hp (480/600 V, 3-phase), enabling reliable isolation of large motors on conveyors, pumps, and presses. This translates to longer motor life, reduced maintenance, and improved plant uptime in demanding manufacturing environments. Four-pole, fusible without neutral design simplifies wiring for multi-line circuits and ensures a complete disconnect across all phases, reducing the risk of linger energization during maintenance. This also streamlines installation in control panels and switchgear assemblies, delivering a safer, faster commissioning process with fewer field wiring errors. The NEMA 1 enclosure in painted steel provides interior protection suitable for dry, indoor environments, while the Class H fuse provision delivers fast-acting protection for short-circuit events. This combination supports compliance with common electrical codes and reduces the total cost of ownership by limiting corrosion and maintenance needs. UL Listed certification underpins safety and reliability, complemented by a one-year warranty (or 18 months from shipment per policy), giving technicians confidence during installation and service. Users benefit from reduced risk and clearer procurement specifications when specifying motor-disconnect gear for new builds or retrofits. Conductor termination accepts substantial feeder sizes, including up to (#2–600 kcmil) Al and (#1/0–750 kcmil) Al configurations, enabling flexible feeder design and future system expansion without replacing switchgear. This reduces retrofit costs and supports long-term electrical corridor planning. Overall, the DH466FGK combines robust protection, straightforward installation, and scalable current handling to support uptime, safety, and compliance in industrial power-distribution and motor-control applications.
