FAQs
The DH266NGKLPR is a two-pole, fusible switch rated for 600A at 600V and uses a solid neutral. Plan for a NEMA 1 indoor enclosure with appropriate panel space, considering its substantial footprint (approximately 23.66 in wide, 51.82 in tall, 14.07 in deep) and a weight around 135 lb. Utilize the Posi-Lok reverse pin features to ensure secure, fast wiring and reliable field assembly alongside compatible Eaton switching devices.
Fusible with solid neutral provides clear fault clearing paths and stable neutral performance, reducing the risk of neutral-floating faults that can compromise motor protection and control logic. This arrangement simplifies fuse replacement during maintenance and supports predictable downtime planning, which helps maintain line uptime and minimizes arc-flash exposure during service or testing.
The DH266NGKLPR is designed for indoor, dry locations due to its NEMA 1 enclosure rating. It is well suited for motor control centers, power distribution panels, and machine control applications within manufacturing plants where indoor protection and high-current isolation are required. For outdoor or harsh environments, consider enclosure upgrades or alternative IP-rated products.
This switch is UL Listed, indicating compliance with recognized safety standards for electrical equipment, which supports formal audits and qualification processes. The NEMA 1 enclosure rating further confirms suitability for indoor dry environments. Combined, these certifications help streamline compliance documentation and reduce project risk during installation and commissioning.
Eaton provides a warranty under its policy 25-000, typically one year from installation or eighteen months from shipment, whichever occurs first. This coverage, along with UL listings and robust build, reduces maintenance surprises and shortens payback periods by limiting unscheduled downtime and repair costs. Access to Eaton support materials enhances troubleshooting and lifecycle planning.
