Eaton Specification Sheet - DH427SNRKLCR
Feature: 800A amperage rating with four poles provides robust capacity for large motor loads. Business Impact: minimizes unplanned outages and reduces the need for multiple disconnects in high-load feeders. Application: motor control centers and main feeders in manufacturing plants. In practice, this enables tighter protective coordination and faster isolation during maintenance. The result is improved safety and equipment protection with lower life-cycle costs. Feature: Fusible with switched neutral enhances selective tripping and fault energy control. Business Impact: improves protective coordination and reduces arc-flash exposure during disconnection. Application: feeders feeding critical loads and process lines in harsh environments. This supports compliant maintenance procedures and safer startup sequences. Feature: NEMA 3R enclosure offers weather-resistant outdoor performance. Business Impact: enables reliable outdoor operation without additional housings, lowering installation complexity. Application: outdoor substations, outdoor switchgear rooms, and exterior process areas. This reduces downtime and maintenance visits while preserving enclosure integrity. Feature: Series K with Cam-Lok reverse pin enables fast, secure wiring and easy field servicing. Business Impact: shortens commissioning time and minimizes wiring errors, boosting uptime. Application: large facilities with frequent maintenance cycles and modular replacement needs. This design choice supports safer, faster turnarounds and consistent performance. Feature: UL Listed certification and rugged construction provide confidence in safety compliance and long-term reliability. Business Impact: reduces procurement risk and supports standardization across sites. Application: enterprise-wide rollout in industrial environments, including manufacturing and distribution centers. The device’s dimensions and weight (32.87 in L, 85.59 in H, 21.73 in W, 540 lb) should be planned for with appropriate handling equipment, ensuring proper support and alignment during installation.

FAQs
The DH427SNRKLCR is designed for integration into typical industrial power-distribution layouts and can be mounted in standard switchgear configurations that support four-pole, 800A disconnects. It uses Cam-Lok reverse pin connections for fast, secure wiring, reducing field wiring errors and installation time. Ensure compliant mounting hardware and sufficient clearance for a 540 lb unit, and plan for a lifting device or pallet jack during installation.
Key specs include an 800A amperage rating, four-pole configuration, 240V voltage rating, and a fusible with switched neutral arrangement. The unit is UL Listed and features a Series K design with NEMA 3R enclosure, supporting safe outdoor installation and reliable fault protection across critical feeders and motors.
This safety switch excels in heavy-duty motor control, outdoor substations, and large-scale power-distribution scenarios found in manufacturing, processing, and distribution facilities. Its rugged build and weather-resistant enclosure make it ideal for outdoor service areas, while the fusible with switched neutral supports selective protection for important process lines.
The DH427SNRKLCR carries UL Listed certification, indicating compliance with recognized safety standards. The enclosure is rated NEMA 3R for outdoor use. These certifications support procurement workflows by reducing risk and helping meet internal safety and regulatory requirements for industrial installations.
With a robust 800A, 4P design and Cam-Lok fast-wiring, maintenance cycles are shorter and downtime is minimized during servicing. The unit’s safety features and UL certification help lower compliance risk, while its heavy-duty construction supports a longer service life in demanding environments, contributing to lower total cost of ownership over time.
