DEI Power operates as an approved Siemens OEM, meaning every assembly uses verified genuine Siemens components for trusted code compliance.

Switchgear typically refers to assemblies designed for higher fault-current interrupting capability and more robust protection, often used in utility, service entrance, and critical industrial applications. Switchboards are generally used for power distribution within a facility where branch circuit protection and metering are the primary functions. Both product types in DEI Power's lineup are UL 891 certified and built with genuine Siemens components.

All DEI Power switchgear, switchboards, SES sections, and meter mains are available in NEMA 1 enclosures for indoor installations and NEMA 3R enclosures for outdoor or weather-exposed environments. NEMA 3R enclosures provide protection against rain, sleet, and external ice formation, making them suitable for rooftop, outdoor pad-mount, and service entrance applications.

DEI Power's product line supports a wide range of voltage configurations including 120/240V, 208Y/120V, 240V, 240/120V, 480V, 480Y/277V, and 415/240V. Multi-voltage options are available across switchgear, switchboards, service entrance units, SES sections, and meter mains, providing the flexibility needed for domestic commercial, industrial, and international utility projects.

DEI Power's switchgear and power distribution products serve a broad range of industries including commercial buildings and campuses, data centers and colocation facilities, industrial manufacturing, utility infrastructure projects, healthcare facilities, and hyperscale enterprise environments. Products are engineered to handle critical loads where power reliability and code compliance are non-negotiable requirements.
