Custom Switchgear Systems & Solutions

A switchgear is an electrical distribution assembly that controls, protects, and isolates power systems. It typically houses breakers, bus bars, protective devices, and control components in a structured enclosure. In commercial and industrial settings, switchgear helps manage incoming power safely, supports maintenance access, and protects connected equipment from overloads, faults, and operational disruptions.

The main components of switchgear usually include circuit breakers or disconnects, bus bars, protective relays, metering devices, control wiring, and enclosure sections. Depending on the application, systems may also include monitoring equipment, surge protection, and service access features. Together, these components distribute power, isolate faults, and support safer operation, maintenance, and system coordination.

The main purpose of metal clad switchgear is to provide a high level of safety, compartmentalization, and fault isolation in medium-voltage applications. Its separated compartments help limit the spread of electrical faults and improve maintenance access. This design is commonly used in utilities, industrial plants, and critical infrastructure where reliability, protection, and serviceability are essential.

A switchgear assembly is a complete, integrated lineup of electrical distribution equipment built into one coordinated system. It may include multiple sections for main incoming power, feeders, breakers, controls, and metering. The assembly is engineered to meet specific voltage, amperage, enclosure, and compliance requirements so it can be installed as a unified solution for the facility.

Choosing the right system starts with load requirements, voltage, available space, enclosure type, utility standards, and the level of protection needed. DEI Power helps review specifications, ratings, layouts, and integration requirements before order release. That process helps reduce mismatches, supports submittal approval, and ensures the final assembly aligns with installation conditions and long-term operating demands.

Yes. DEI Power provides UL 891-certified low-voltage switchgear and supports projects with compliance documentation, submittals, and specification guidance. Certain service entrance solutions are also UL listed, EUSERC approved, and built to meet UBC, CBC, and IBC seismic requirements where applicable. This documentation helps contractors, engineers, and procurement teams move through review and approval more efficiently.

Shipping timelines vary by product and configuration, but many stocked orders ship within 1 business day, with some orders requiring up to 5 business days. DEI Power also offers free shipping on qualifying orders delivered in 3-5 business days. Their Ontario, California warehouse and in-house manufacturing capabilities help support faster fulfillment for time-sensitive projects nationwide.

Yes. DEI Power offers engineering support and design services for custom layouts, ratings, component coordination, and integration with existing systems. The team can assist with electro-mechanical schematics, CAD layouts, finalized drawings, and submittal documentation. This support helps improve installation readiness, reduce field adjustments, and keep projects aligned from concept through production and commissioning.
