FAQs
Installation requires a compatible three-pole, three-wire setup with non-fusible switching. Verify support for a 240V distribution circuit, ensure the NEMA 3R enclosure provides the required environmental protection, and follow Eaton wiring diagrams for proper terminal connections. The device’s 16 in depth and 26.58 in width should fit standard industrial enclosures; use hoisting equipment for safe assembly.
The 100A amperage rating supports high-load circuits, while the 240V voltage rating defines the system voltage the switch is designed to interrupt. As a non-fusible, three-pole switch, it provides reliable control for three-wire motor circuits and reduces the need for frequent fuse replacements, improving uptime in production lines.
Yes. The NEMA 3R enclosure, along with painted galvanized steel construction, is designed for outdoor and harsh-environment installations. This combination offers protection against moisture, dust, and incidental contact, helping maintain reliable operation in outdoor switchgear and distribution panels.
The DH323URKA1208 carries UL Listed safety certification and is housed in a NEMA 3R enclosure. These credentials support code compliance, safer integration into medical-free zones, and reduced risk during commissioning and maintenance in industrial facilities.
Eaton provides a warranty policy (25-000) offering one year from installation or eighteen months from shipment, whichever occurs first. This coverage, combined with UL certification and documented specifications, supports predictable maintenance planning and lower lifecycle costs for mission-critical distribution panels.
