FAQs
Outdoor or harsh environments require using the NEMA 3R-rated enclosure and proper mounting clearances. Plan for adequate panel access and cooling, correct wiring methods for three-phase circuits, and accommodate the unit's substantial weight (~140 lb) with suitable mounting hardware and supports. Follow local codes for grounding and protective covers to ensure long-term reliability.
DH364FRKLPR is rated at 200 A and 600 V with three poles and a fusible configuration. Fusible means the switch is intended to be used with fuses in the protected circuit, providing controlled interrupting capability and fault current limiting. This arrangement supports safe motor starting and protection coordination with downstream devices and protective relays.
Yes. The NEMA 3R enclosure provides protection against rain, dust, and corrosion, making it suitable for outdoor substations and outdoor process areas. UL Listed certification confirms safety compliance. For extreme conditions, verify installation ratings, seals, and periodic maintenance per Eaton guidelines to ensure ongoing reliability.
UL Listed indicates the product meets established safety standards for electrical equipment, supporting regulatory compliance and simplifying audits. In this model, UL Listed together with the NEMA 3R enclosure rating enhances confidence during design reviews and inspections. Always align with local codes (NEC, NFPA 70) and industry requirements for your specific sector.
Posi-Lok reverse pin ensures precise alignment during operation and maintenance, reducing mis-seating and wiring errors. It provides tactile feedback and secure engagement, which lowers rework and downtime during fuse changes or inspections. This feature improves reliability on high-availability lines and speeds routine servicing without compromising safety.
