Low-Voltage Switchgear
SWITCHBOARD
UL 891 Listed · Dead-Front · NEMA 1 / 3R
The CODI UL 891 Switchboard is an engineer-to-order, dead-front distribution assembly built for main service entrance, main distribution, and emergency power applications across commercial, industrial, and mission-critical facilities. Each unit is code-compliant and configured to your project's voltage, ampacity, fault current rating, breaker brand. Independently manufactured in Littleton, Colorado with full UL 891 listing, complete engineering documentation, and shorter lead times than national OEMs.

KEY FEATURES
Custom Configuration
Engineered to your project's exact voltage, ampacity, fault current, and breaker requirements — not a catalog solution.
UL 891 Listed Dead-Front
Every switchboard ships UL 891 listed as a dead-front assembly, preventing access to live bus and components during normal operation.
High-Capacity Bus
Main bus ratings from 400A to 6000A; silver-plated copper or tin-plated aluminum bus available.
High Fault Current Ratings
Short-Circuit Current Ratings (SCCR) up to 200kAIC to match facility fault current requirements.
Multi-Brand Breaker Compatibility
Accommodates molded-case and insulated-case circuit breakers from major manufacturers (Siemens, Eaton, ABB, etc.) — no proprietary lock-in.
Enclosure Options
TYPE 1 (indoor) and TYPE 3R (outdoor) configurations; stainless steel available for corrosive environments.
