FAQs
For proper installation, mount in a NEMA 1 indoor enclosure and follow the two-pole, fusible without neutral configuration. Ensure space for a neutral or ground lug kit if service entrance use is anticipated. Verify conductor sizing to match the max fuse and ampacity requirements, and confirm compatible wiring methods per NEC guidelines to maintain the 230.62 barrier integrity.
The DH265FGK supports 400 A and a 600 V rating with a two-pole configuration and fusible without neutral. It accepts conductors up to (2) 300 kcmil or (1) 750 kcmil aluminum or equivalent copper, enabling large motor protection and high-load applications while maintaining NEC-compliant protection and reliable disconnects.
Yes. The switch is UL Listed and features a NEC 230.62 (C) compliant barrier, making it suitable for service entrance installations in compliant electrical rooms and distribution panels. This certification streamlines approvals during audits and ensures safety performance aligned with industry standards.
Ideal for service entrances, heavy machinery panels, and control cabinets where 400 A protection and 600 V isolation are required. It supports high horsepower loads (up to 50 HP at 250 V DC) and large conductor runs, making it suitable for manufacturing, processing, and material handling environments that demand robust protection and reliable operation.
The durable painted steel enclosure and Class H fuse design deliver predictable replacement cycles, reducing unexpected outages. UL listing and NEC compliance simplify regulatory checks, while the compact footprint and lug-kit compatibility improve installation efficiency and lifecycle costs. Warranty provisions, including Eaton’s policy, provide added protection against early failures and support long-term asset reliability.
