Eaton Specification Sheet - DH364URKNLC
The 200A, three-pole, 600V rating provides robust isolation for high-current motor control. This capability reduces arc energy and protects downstream equipment during maintenance and startup, translating to fewer unplanned outages. It is well-suited for conveyors, pumps, and other line-side loads in manufacturing and processing facilities. Cam-Lok connections simplify field wiring, delivering faster, more reliable terminations with reduced installation time and fewer loose connections, cutting labor and rework costs. When retrofitting or expanding control panels, Cam-Lok enables repeatable, vibration-resistant connections in harsh environments. The NEMA 3R weather-resistant enclosure supports outdoor or damp locations, minimizing corrosion risk and wiring exposure for uptime in outdoor substations or equipment rooms. This compatibility helps facilities meet environmental codes while maintaining safe accessibility for servicing. Unfused configuration simplifies panel design where protection is provided upstream, reducing internal maintenance points. For projects requiring external protection, the DH364URKNLC integrates cleanly without redundant devices. Series K heavy-duty design ensures dependable performance within Eaton's protection ecosystem, easing spare-parts sourcing and maintenance. UL Listed certification and a clear warranty backdrop provide regulatory assurance and long-term support for audits and lifecycle planning.

FAQs
The DH364URKNLC is designed for three-phase motor control and power isolation in industrial environments. With a 200A, 600V rating and a NEMA 3R enclosure, it suits conveyors, pumps, and fans in manufacturing, utilities, and process facilities. The Cam-Lok connections support quick wiring, making it ideal for retrofit projects and new installations where robust protection and fast commissioning are required.
This model is unfused, meaning it does not contain internal fuses. Circuits must be protected upstream or by downstream protection devices per applicable codes. This design simplifies integration into existing protection schemes and allows precise selection of overcurrent devices based on your system architecture and safety requirements.
Yes, the DH364URKNLC is UL Listed, indicating compliance with recognized safety standards. It features a NEMA 3R enclosure suitable for outdoor and damp indoor environments, providing weather resistance and reliable performance in harsh conditions typical of outdoor substations, waste-water plants, and outdoor equipment rooms.
Cam-Lok connections offer fast, secure, vibration-resistant terminations that reduce field wiring time and the likelihood of loose connections. This improves installation reliability, lowers labor costs, and simplifies maintenance in environments with frequent vibration or temperature fluctuations, making it a preferred choice for panel assemblies and retrofit projects.
Eaton provides a warranty aligned with its standard policy: one year from installation or eighteen months from shipment, whichever occurs first. This, combined with UL Listing and robust enclosure design, supports lifecycle planning and reduces unexpected maintenance costs, particularly important for critical industrial applications and compliance audits.
