4000 Amp Metal Enclosed Switchgear

480V switchgear refers to metal enclosed power distribution equipment rated for 480V or 480Y/277V three-phase systems — the most common voltage class in commercial and industrial facilities in North America. DEI Power's 480V switchgear is available in NEMA 1 and NEMA 3R enclosures, is UL listed, and is built with genuine Siemens components for reliable performance.

DEI Power's 4000 Amp switchgear lineup is UL Listed, UL 891 certified for low-voltage switchgear assemblies, and EUSERC approved for service entrance applications. Products also meet UBC, CBC, and IBC seismic zone requirements, making them suitable for projects in all seismic zones across the United States.

DEI Power's 4000A switchgear and switchboards are available in multiple voltage configurations including 120/240V, 208Y/120V, 240V, 240/120V, 480V, 480Y/277V, and 415/240V. This flexibility ensures the right solution for a wide variety of commercial, industrial, and utility power distribution requirements.

NEMA 1 enclosures are designed for indoor use, providing protection against contact with live parts in clean, dry environments. NEMA 3R enclosures are rated for outdoor use, offering protection against rain, sleet, and external ice formation. DEI Power offers both enclosure types across their 4000A switchgear and switchboard product lines.

Yes. Because switchgear must be built to approved utility specifications, DEI Power does not accept direct online orders for service entrance equipment. Customers work with a DEI Power specialist to configure voltage, amperage, NEMA rating, and layout to meet specific jobsite and utility requirements.

4000A metal enclosed switchgear is used across data centers and colocation facilities, commercial buildings and campuses, industrial manufacturing plants, utility and infrastructure projects, and healthcare facilities. Any environment requiring high-capacity, reliable, and code-compliant power distribution at the service entrance or main distribution level is a candidate for this equipment.
