1200A I-Line Panelboards

DEI Power offers I-Line panelboards in a wide range of amperage ratings including 400A, 600A, 800A, 1000A, 1200A, 1600A, 2000A, 2500A, 3000A, and 4000A. The 1200A configuration is ideal for high-demand commercial and industrial installations that require substantial power distribution capacity without stepping up to larger switchgear.

These panelboards are available in multiple voltage configurations to suit diverse project needs: 120/240V, 208Y/120V, 240V, 240/120V, 480V, 480Y/277V, and 415/240V. This flexibility allows contractors and engineers to specify the correct system voltage for commercial buildings, industrial facilities, or utility infrastructure without requiring custom one-off builds.

NEMA 1 enclosures are rated for indoor use in dry, clean environments, providing protection against accidental contact with live components. NEMA 3R enclosures are designed for outdoor or partially exposed installations, offering protection against rain, sleet, and ice formation. Selecting the correct NEMA rating ensures equipment longevity and compliance with installation code requirements for your specific environment.

Yes. All DEI Power 1200A I-Line Panelboards are UL 891 certified and EUSERC approved. UL 891 certification confirms the assembly meets rigorous safety and performance standards for low-voltage panelboards. EUSERC approval confirms compliance with Electric Utility Service Equipment Requirements, which is required for utility metering and interconnection applications across many utility service territories.

Yes. All panelboards are built to meet seismic zone requirements under the Uniform Building Code (UBC), California Building Code (CBC), and International Building Code (IBC). This makes them suitable for installation in seismically active regions including California and other high-seismic zones, without requiring additional seismic bracing or third-party certification.
