Selling Policy 25-000 - Distribution and Control Products and Services
High-current capability enables uninterrupted feeders and rapid switchgear control, reducing unplanned downtime and safeguarding operators during maintenance. This aligns with production lines that demand dependable power during peak loads and in-rush events. The rugged NEMA 3R enclosure provides reliable protection in outdoor or damp environments, ensuring continued operation across weather conditions and ambient contaminants. Cam-Lok connections simplify installation and enable secure, fast field wiring, lowering labor costs and setup time on busy plant floors. Fuse configuration as fusible with solid neutral delivers predictable fault clearing and safer, more maintainable switching sequences, contributing to longer equipment life and easier fuse replacement cycles. Series K compatibility and a heavy-duty construction support long-term lifecycle management, while UL Listed certification reinforces compliance with prevalent electrical safety standards and audit readiness. For installation teams, the unit’s substantial weight and dimensions (32.87 in depth, 85.59 in height, 21.73 in width, 540 lb) underscore the need for appropriate lifting equipment and planning to minimize site disruption.

FAQs
Installation requires planning for a three-pole, 800A device with significant physical dimensions (32.87 in depth, 85.59 in height, 21.73 in width) and a 540 lb weight. Ensure suitable lifting equipment, secure mounting in an appropriate enclosure or pad, and compatible wiring and Cam-Lok connections. Adhere to electrical codes and Eaton’s installation guidelines to minimize downtime during panel integration and commissioning.
The DH327NRKLC is rated for 800A and 240V with three poles in a fusible with solid neutral configuration. It uses a Series K design and employs a NEMA 3R enclosure suitable for indoor and outdoor installations. This combination supports reliable control of high-current feeders and safe fault clearing in industrial power distribution.
Yes. The unit features a NEMA 3R enclosure, designed for outdoor and harsh-environment applications, enabling safe operation in wet, dusty, or corrosive settings. This makes it well-suited for outdoor substations, exterior equipment rooms, and exposed plant locations, while maintaining protection during weather events and routine maintenance.
The DH327NRKLC carries UL Listed certification, confirming adherence to recognized electrical safety standards. Its rugged construction and enclosure rating (NEMA 3R) complement this certification, supporting compliance during audits and in regulated facilities that require documented safety and reliability for high-current switching.
Plan periodic inspections of fusible components and solid-neutral connections, and schedule fuse replacements as part of preventive maintenance. Cam-Lok connectors should be checked for secure engagement and signs of wear. Given the switch’s size and weight, arrange proper lifting and installation procedures to minimize downtime during maintenance or component replacement and to ensure operator safety.
