Eaton Specification Sheet - DH328UGKNLC
Feature: 1200A amperage rating paired with a three-pole, 240V configuration. Business impact: Enables safe, single-point switching for high-demand motors and feeders while minimizing voltage drop and arc exposure. Application: suitable for heavy-duty motor control in manufacturing lines and process plants. The real-world benefit is reduced downtime during startup and fault events, translating to lower total cost of ownership. Feature: Non-fusible with solid neutral. Business impact: simplifies control philosophy and reduces component count, lowering lifecycle maintenance costs while preserving reliable fault isolation. Application: ideal for distribution panels and essential service feeds where a non-fusible topology is preferred. Feature: Cam-Lok quick-connect terminals. Business impact: speeds field wiring, reduces miswiring risks, and shortens installation cycles by eliminating complex terminal torque procedures. Application: field retrofit projects and new builds where fast commissioning matters. Feature: NEMA 1 enclosure with indoor suitability. Business impact: provides robust enclosure protection against dust and incidental contact in indoor environments, supporting uptime in demanding facilities. Application: indoor switchgear rooms, control panels, and electrical rooms. Feature: UL Listed with Series K design. Business impact: reinforces compliance with safety standards and compatibility with Eaton systems, enabling smoother approvals and safer maintenance workflows. Application: integration into certified electrical distribution schemes and panel assemblies. Together these features deliver measurable outcomes: faster installation, safer operation under high currents, and reliable performance in industrial environments while maintaining compatibility with common switchgear and control architectures.

FAQs
The DH328UGKNLC uses Cam-Lok terminations and a solid neutral, simplifying retrofit installs into compatible three‑pole, 240V systems. Ensure enclosure suitability (NEMA 1 indoor) and verify UL Listed compliance with your panel design. Plan wiring routes to minimize bend radii and maintain clearances around the 1200A service path.
A 1200A rating provides ample current capacity for large motors and feeders, reducing thermal stress during startup and fault events. Controlled switching minimizes arcing and improves reliability. For safety, rely on UL Listed certification and adherence to proper enclosure installation per NEMA 1 guidelines.
No. The enclosure is NEMA 1 rated, which is intended for indoor use or sheltered environments. For outdoor or harsh conditions, select a unit with a higher enclosure rating (e.g., NEMA 4X) and verify compatibility with your hvac and environmental controls.
The DH328UGKNLC is UL Listed and designed into a NEMA 1 indoor enclosure. This combination supports safety compliance in standard industrial facilities and aligns with typical electrical installation practices in controlled environments.
Cam-Lok terminations reduce wiring time and wiring errors, cutting commissioning and maintenance labor. The design minimizes recurring maintenance needs and supports quicker upgrades or expansions, delivering lower total cost of ownership over the product life cycle.
