FAQs
The DH464SNRKLC is designed for four-pole, 200A, 600V motor feeders and power-distribution circuits. Its Cam-Lok quick-connects simplify field wiring, and the NEMA 3R enclosure supports indoor and outdoor installations. When planning retrofits or new builds, verify bus-bar compatibility, mounting footprint, and panel clearances to ensure a seamless integration with existing switchgear.
Key specs include 200A amperage rating, 600V voltage rating, four poles, single-throw operation, fusible with switched neutral, Series K construction, Cam-Lok connectivity, and UL Listed certification. Enclosure is NEMA 3R, and dimensions are 18.57 in depth, 40.89 in height, and 13.68 in width, with an approximate weight of 140 lb.
Yes. The DH464SNRKLC uses a NEMA 3R enclosure, which provides protection against rain, dust, and corrosion in outdoor or harsh indoor environments. This makes it suitable for outdoor equipment rooms and exposed installations, while maintaining safe isolation operations for critical loads up to 200A.
The DH464SNRKLC is UL Listed, signaling compliance with recognized electrical safety standards. The enclosure rating (NEMA 3R) adds environmental protection context, supporting its use in both indoor and outdoor settings. It is important to reference these certifications during safety audits and procurement reviews.
Maintenance considerations include routine inspection of connections and the neutral/fuse path as part of standard electrical safety practices. The rugged Series K construction and UL Listed status help reduce unplanned downtime, while Cam-Lok connections speed up servicing. The combination supports lower maintenance costs, improved uptime, and a faster return on investment in industrial environments.
