HD364NFTB Safety Switch: 600A, 4-Pole, 600V (NEMA 3R) — Fusible or Non-Fusible

NEMA 3R weather protection means this switch is suitable for outdoor installations and environments where moisture, dust, or incidental weather exposure must be managed without compromising safety or performance. The enclosure design contributes to long-term reliability in harsh or remote sites, giving you peace of mind that critical equipment can be safely isolated when needed.

Configurable for Fusible or Non-Fusible applications—the HD364NFTB is offered in both configurations, giving you flexibility to match internal protection schemes and spare-part strategy without sourcing entirely different SKUs. This adaptability is especially valuable when aligning with existing BOMs and field maintenance workflows.
