FAQs
The DH365FRKLLV is a three-pole, fusible safety switch designed for 400 A at 600 V in a NEMA 3R enclosure. Plan for a tall, floor-standing installation with clearance for conductor terminations and access to line/load labeling. Ensure compatibility with standard Eaton K-Series accessories and follow NEC guidelines for barrier spacing.
Verify a 400 A current rating, 600 V voltage rating, three-pole, three-wire configuration, and Class H fuse provision. Confirm fusible without neutral operation and ensure conductor sizes up to (2) 300 kcmil Al or (1) 750 kcmil Al equivalents. Also check UL Listed certification and NEC 230.62 barrier compliance.
Yes. It features a NEMA 3R enclosure with painted galvanized steel construction, offering weather resistance for outdoor installations and damp indoor spaces. This makes it appropriate for exterior feeders and protection of critical electrical equipment in challenging environments.
The unit is UL Listed and NEC 230.62 barrier compliant. It uses a NEMA 3R enclosure and is designed for safe operation in industrial settings, aligning with common safety and electrical installation standards for heavy-duty safety switches.
The DH365FRKLLV's enhanced visibility features, clear line/load labeling, and robust Class H fuse design reduce maintenance time and mis-wiring risk.
