Eaton Specification Sheet - DH326SNRKLPR
Feature: 600A, three-pole, 240V capability enables safe isolation of high-current motor feeders. This reduces arc flash exposure and improves fault containment, translating to shorter outage times and safer maintenance windows. Application: ideal for large motor drives, compressors, and process lines in three-phase manufacturing environments. Feature: NEMA 3R enclosure with UL Listed certification provides outdoor and damp-location protection. This combination enhances reliability in harsh environments and reduces enclosure-related failure modes, suitable for outdoor switchgear and exposed installations. Feature: Fusible with switched neutral improves fault isolation and coordination with upstream protection, simplifying wiring and maintenance. Application includes feeder disconnects and critical process circuits where clean disconnection is essential. Feature: Posi-Lok reverse pin enables quick, secure field wiring and easy orientation in tight spaces, reducing installation time and mis-wiring risk. Feature: Series K architecture supports compatibility with Eaton’s switching devices, enabling straightforward retrofits and modular installations in existing industrial estates.

FAQs
For three-phase installations, mount the unit on a stable enclosure with proper clearances, connect the three hot lines to the poles, and wire the fusible with switched neutral per the Series K guidelines. Ensure grounding is compliant and verify terminal torque specifications to prevent loose connections that could cause overheating.
The 600A rating supports large motor feeders and high-load feeders while maintaining safe isolation during disconnection. At 240V, the device delivers robust fault isolation, reduces contact wear, and improves protection coordination with upstream breakers in industrial plants.
Yes. The NEMA 3R enclosure provides weather-resistant protection, and UL Listing confirms compliance with safety standards for outdoor and damp locations. This makes it a reliable choice for exterior switchgear and outdoor control panels in harsh environments.
Posi-Lok reverse pin facilitates quick orientation and secure mating of the switch components during installation. This reduces wiring errors, speeds up commissioning, and improves long-term reliability in crowded electrical rooms or retrofit projects.
The DH326SNRKLPR combines a rugged build with simple wiring, lowering maintenance frequency and downtime. Its durable enclosure and reliable UL Listed performance translate to longer service intervals, fewer unplanned outages, and faster return on investment in high-demand industrial environments.
