Eaton Specification Sheet - DH366SNGKLPR
Feature → Business Impact → Application: The DH366SNGKLPR is a three-pole, heavy-duty safety switch rated at 600A and 600V, enabling safe isolation for large industrial drives and panels. This configuration reduces the risk of arc flash incidents and ensures predictable shutdowns, which translates to safer start-up procedures for manufacturing equipment. Application-wise, it fits high-capacity control circuits in packaging lines or process automation where reliability is critical and space is constrained. Feature → Business Impact → Application: Fusible with switched neutral simplifies wiring and maintenance by consolidating the fuse path and control neutral, reducing wiring errors and downtime during fuse changes. This is particularly valuable in retrofit projects where panel rewiring is a constraint. Feature → Business Impact → Application: NEMA 1 enclosure and rugged Series K construction provide dependable indoor protection against dust and incidental impacts, increasing equipment life in challenging plant environments. This supports uptime targets in tier-one manufacturing. Feature → Business Impact → Application: Posi-Lok reverse pin ensures secure, easy engagement during installation or maintenance, cutting commissioning time and lowering the likelihood of misalignment on multi-branch switchgear. Ideal for electricians upgrading to quick-connect, heavy-duty solutions in new builds or retrofits. Feature → Business Impact → Application: UL Listed certification offers confidence in safety compliance and procurement approvals, reducing validation time and accelerating project timelines in regulated facilities. This is especially important for facilities seeking formal safety attestations within industrial automation and electrical protection workflows.

FAQs
The DH366SNGKLPR is a three-pole, 600A, 600V safety switch designed for standard industrial control panels. It supports fusible with switched neutral wiring and a Posi-Lok reverse pin for secure engagement. Compatible installations typically involve 600V three-phase feeder circuits in indoor enclosures with NEMA 1 protection, as documented in the Eaton specifications.
Key ratings include 600A amperage and 600V voltage, three-pole operation, NEMA 1 enclosure, and a fusible configuration with switched neutral. The device is UL Listed, which validates safety compliance. The Posi-Lok reverse pin aids safe and reliable engagement, while Series K denotes the rugged, heavy-duty construction for demanding environments.
Yes. With a three-pole design, 600A/600V rating, and a NEMA 1 enclosure, the switch is well-suited for indoor industrial applications such as manufacturing lines, packaging machinery, and other control panels where reliable safe isolation is required and space is a consideration.
The DH366SNGKLPR carries UL Listed certification, ensuring compliance with widely recognized safety standards. Its NEMA 1 enclosure supports dust protection in indoor environments. While not all regional certifications are listed, UL Listing provides a strong baseline for regulatory compliance in many markets and simplifies procurement approvals.
Maintenance benefits include easier wiring and safer, faster maintenance with the fusible switched-neutral configuration and Posi-Lok engagement. This can shorten downtime during fuse changes and commissioning. The robust Series K construction and UL Listing contribute to longer service life and reduced total cost of ownership in capital-intensive automated facilities.
