FAQs
The DH366SNGKLCR is a three-pole, heavy-duty safety switch designed for indoor installations in NEMA 1 enclosures. Plan for a footprint compatible with a large disconnect device, using Cam-Lok reverse pin connections for fast wiring. With a length of 32.87 in, height of 74.34 in, and width of 16.1 in, ensure adequate clearance for service access and cable routing. The 370 lb weight indicates a secure, rigid mount, best suited for reinforced panels or mounting rails within a control cabinet or standalone safety switch enclosure.
This switch is rated for 600A and 600V, three-pole operation, which enables safe disconnection of high-current loads such as large motors and controlled equipment. The fusible with switched neutral configuration adds selectivity and protection, while the Series K design supports integration with Eaton’s protective devices. These ratings translate to robust performance in industrial power distribution and reliable protection during abnormal conditions.
The product is specified with a NEMA 1 enclosure, which is intended for indoor, dry environments. It is not rated for outdoor exposure or severe weather without additional protection. For outdoor or harsh environments, consult Eaton for an enclosure option with higher ingress protection (IP rating) or a weatherproof variant and adapt installation accordingly to maintain safety and compliance.
The DH366SNGKLCR carries UL Listed certification, confirming compliance with recognized safety standards for electrical equipment. This certification is essential for many industrial facilities and helps ensure product reliability and safety in electrical installations. While UL Listed is the primary certification here, always verify any site-specific regulatory requirements (local codes, industry standards) when planning installation and maintenance.
Eaton provides a warranty per policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. Maintenance recommendations include periodic inspection of fuse elements, connectors, and wiring terminations, with attention to the Cam-Lok reverse pin connections for secure integrity. Proper maintenance minimizes unexpected outages, extends service life, and supports predictable ROI in critical production lines.
