FAQs
For retrofit work, plan for two-pole operation with 800A capacity and 240V supply. Ensure proper mounting within a NEMA 3R space and maintain clearances for service access. Use the Posi-Lok feature to achieve positive handle position during commissioning and verify solid neutral connections per local electrical codes. Follow Eaton documentation and local standards for wiring methods.
The 800A rating denotes the switch’s ability to safely interrupt and isolate high-current fault events, protecting equipment and personnel. It supports robust disconnect capability in heavy-duty circuits, reduces arc exposure, and minimizes downtime by enabling rapid, secure isolation of energized loads in industrial environments.
Yes. The DH227NRKLP uses a Series K design with a NEMA 3R enclosure, providing protection against rain, dust, and environmental contaminants. This makes it appropriate for outdoor installations and damp indoor spaces, while UL Listed certification reinforces compliance with safety standards for rugged industrial use.
The product carries UL Listed certification, ensuring recognized safety compliance for electrical equipment. It is designed with a NEMA 3R enclosure for environment protection and adheres to Eaton’s Series K specifications. Always verify local regulatory requirements and facility standards to ensure full alignment with project-specific certification needs.
Posi-Lok provides a positive, locked-in position for the handle, reducing risk of inadvertent re-closure and streamlining maintenance and testing workflows. This translates to lower downtime during inspections, quicker reset after servicing, and improved reliability in routine operations, thereby contributing to lower lifecycle costs for high-availability plants.
