Outdoor Pad-Mounted Switchgear

Pad-mounted switchgear controls, protects, and distributes electrical power at the point where utility service enters a facility. Mounted on a concrete pad outdoors, it houses main breakers, service entrance components, and distribution equipment. It serves as the primary interface between the utility supply and a building's internal electrical system, enabling safe load management and circuit protection.

Outdoor switchgear refers to electrical switching and protection equipment housed in weather-resistant enclosures — typically NEMA 3R or higher — designed for exterior installation without additional shelter. DEI Power's outdoor switchgear lineup includes switchboards, service entrance switchgear, and SES units rated from 400A to 4000A across multiple voltages, all built with genuine Siemens components and UL 891 certification.

NEMA 3R is the standard minimum enclosure rating for outdoor switchgear applications. It protects against falling rain, sleet, and ice, making it appropriate for pad-mounted installations. DEI Power offers all switchgear products in either NEMA 1 (indoor) or NEMA 3R (outdoor weather-resistant) configurations, allowing customers to select the right enclosure for their specific installation environment.

DEI Power's outdoor pad-mounted switchgear is available from 400A up to 4000A, with incremental ratings including 600A, 800A, 1000A, 1200A, 1600A, 2000A, 2500A, and 3000A. Multiple voltage configurations are supported, including 120/240V, 208Y/120V, 240V, 480V, 480Y/277V, and 415/240V, providing flexibility for diverse commercial, industrial, and utility project requirements.
