FAQs
The 3HD368NFV uses a NEMA 3R enclosure suitable for indoor or outdoor installations. Plan for a fixed, secure mounting surface with adequate clearance for wiring access, inspection, and VIS-BLADE visibility. Ensure compatible hardware is used for 3P connections and that mounting aligns with standard Eaton accessory kits to simplify commissioning.
The unit is rated for 1200A amperage, 3-pole (3P) configuration, at 600V. It is designed for heavy-duty service in high-load distribution panels and feeders, enabling reliable disconnects for large motors and feeders within industrial facilities.
Yes. The 3HD368NFV is a NEMA 3R-rated HDSS device, engineered for outdoor and rugged environments. The enhanced visible blade (VIS-BLADE) aids in safe operation and inspection, while CSA certification confirms compliance with relevant safety standards in demanding industrial settings.
This unit carries CSA Std. C22.2 No. 4 certification (File LL69743), supporting compliance with Canadian electrical safety requirements. In audits, such certifications help verify that the disconnect meets established safety criteria, reducing risk and streamlining regulatory reviews.
The switch’s robust HDSS design, clear blade visibility, and CSA-backed safety reduce maintenance time and risk during servicing, lowering downtime costs. Its durable enclosure and high amperage rating support longer service intervals and scalable protection as facility loads grow, delivering a favorable ROI for continuous operation environments.
