FAQs
The DH325NRKLCR is a three-pole, 400A disconnect designed for standard industrial panels. Plan for a 240V supply and ensure compatible bus bar and housing clearances for a Series K, heavy-duty interior. Cam-Lok reverse pin connections simplify wiring, while the solid-neutral fusible configuration requires correct neutral sizing and fuse coordination per your protection scheme. Check NEMA 3R suitability if the panel faces outdoor or damp environments.
Wire sizing should match 400A current rating with appropriate conductors, and accommodate the three-pole arrangement. Use the Cam-Lok connectors for quick, secure terminations and follow the manufacturer’s installation guide for torque values on access hardware and neutral connections. Ensure proper fuse configuration to maintain intended protection levels and minimize voltage drop across the switch during operation.
Yes, when installed in a NEMA 3R enclosure, the DH325NRKLCR is suited for outdoor or damp environments. The rugged construction, combined with a weather-resistant enclosure, protects internal components from moisture and particulates, reducing maintenance needs. For outdoor installations, verify enclosure sealing, cable ingress, and drainage requirements in accordance with site conditions.
The DH325NRKLCR carries UL Listed certification, providing recognized safety assurance for electrical equipment. Its NEMA 3R enclosure rating supports outdoor and damp locations, aiding compliance with installation codes and standards. While SIL or CE markings are not specified in the data, UL listing and enclosure protection are critical for safe operation and regulatory alignment in many industrial facilities.
Installing the DH325NRKLCR can reduce downtime through rapid fault isolation and fast field wiring via Cam-Lok reverse pins. The solid neutral fusible design promotes reliable protection coordination, potentially lowering maintenance costs and unplanned outages. Its rugged Series K construction supports long service life in demanding environments, delivering predictable lifecycle costs for OEMs and maintenance teams.
