FAQs
For installation, mount the three-pole fusible switch in a compatible enclosure, ensure Cu/Al conductors up to #6-250 kcmil are securely terminated, and follow the NEMA 3R protection guidelines. Verify the 600 V rating aligns with your system voltage and ensure proper clearance around the enhanced visible blades for safe operation.
The DH364FRKLLV is UL Listed and designed as a three-pole, fusible switch with a NEMA 3R enclosure and Class H fuse provisions. Its fusible without neutral configuration simplifies wiring while maintaining robust short-circuit protection, aligning with common industrial safety and electrical protection standards.
This switch is ideal for heavy-duty motor control centers, service disconnects for large feeders, and industrial distribution panels. Its enhanced visible blades, rugged NEMA 3R enclosure, and high current rating make it well-suited for outdoor or harsh indoor environments requiring reliable isolation and protection.
Key certifications and ratings include UL Listed certification and a NEMA 3R enclosure. The device is rated for 200A and 600V, with Class H fuse provision. While not providing IP, SIL, or CE data in the current spec, the UL listing and enclosure rating support common compliance needs in US industrial applications.
The DH364FRKLLV reduces maintenance risk with enhanced blade visibility and robust enclosure protection, minimizing unplanned outages. Its compatibility with Cu/Al conductors up to #6-250 kcmil streamlines wiring, while UL Listed safety reduces compliance overhead. Over time, this can lower downtime, extend mean time between failures, and simplify spare-parts inventory through K-Series compatibility.
