800A 3-Phase 240V Main Circuit Breaker Switchboards

The 800A switchboards are available in two NEMA enclosure ratings: NEMA 1 for indoor installations and NEMA 3R for outdoor or weather-exposed environments. This flexibility allows contractors and engineers to select the appropriate enclosure type based on the installation site's environmental conditions and code requirements.

DEI Power switchboards support a wide range of voltage configurations including 120/240V, 240V, 208Y/120V, 240/120V, 480V, 480Y/277V, and 415/240V. This makes them adaptable to a broad spectrum of commercial, industrial, and utility power distribution requirements across different facility types and grid configurations.
