800A Switchgear — 480V 3-Phase Circuit Breaker

An 800A switchgear assembly is used to distribute and protect high-capacity electrical power in data centers, commercial buildings, industrial facilities, and colocation environments. It serves as a central control point for 480V 3-phase power, managing branch circuit distribution while providing overcurrent protection to downstream loads and equipment.

Yes. All DEI Power switchgear, including 800A assemblies, is UL 891 certified for low-voltage switchboard construction. Units are also built as a Siemens Approved OEM and EUSERC Approved, ensuring compliance with applicable utility, building, and safety codes including UBC, CBC, and IBC seismic requirements.

DEI Power's 800A switchgear supports multiple voltage configurations including 480Y/277V, 208Y/120V, 120/240V, 240V, and 415/240V. For high-density data center and industrial applications, 480Y/277V 3-phase 4-wire configurations are standard, providing efficient power delivery to large electrical loads.

In-stock 800A units typically ship within 1 business day from DEI Power's 50,000 sq. ft. facility in Ontario, California, with job-site delivery in 3–5 business days. Built-to-order and custom configurations carry a typical 4–6 week lead time — significantly faster than the industry-standard 16-week average.

DEI Power's 800A Remote Power Panel (RPP) supports up to 84 branch circuits in full configuration. Optional branch circuit monitoring is available, making it ideal for high-density colocation rows, hyperscale data center pods, AI/GPU compute clusters, and enterprise deployments requiring structured power distribution.

DEI Power's 800A switchgear is available in NEMA 1 (indoor) and NEMA 3R (outdoor weather-resistant) enclosures, providing flexibility across installation environments. NEMA 1 suits controlled indoor data center and commercial settings, while NEMA 3R is appropriate for outdoor or weatherproof installations in utility and infrastructure applications.

DEI Power's 800A lineup includes Remote Power Panels (RPPs), Switchgear, Switchboards, Panelboards, Meter Mains, and Service Entrance equipment (including SES and Service Entrance Switchgear). All products are UL 891 certified, built with genuine Siemens components, and available in NEMA 1 or NEMA 3R enclosures for data center, commercial, industrial, and utility applications.
