Low Voltage Motor Control Centers

MCC switchgear refers to low voltage assemblies that combine motor control functions with switching and protection devices within a single enclosure. These systems manage, protect, and isolate electrical circuits feeding motors and loads. UL 891-certified switchgear assemblies — like those offered by DEI Power — provide code-compliant, reliable power distribution in demanding commercial and industrial environments.

Switchgear is primarily designed for power distribution, circuit protection, and isolation using breakers and disconnect switches. An MCC (Motor Control Center) is specialized for controlling and protecting motor loads using starters, contactors, and drives. While switchgear manages power flow to buses and downstream circuits, MCCs manage the operation of individual motors within a facility's electrical system.

DEI Power's low voltage switchgear and switchboard assemblies are available across a broad range of configurations, including 120/240V, 208Y/120V, 240V, 480V, 480Y/277V, and 415/240V. Amperage ratings span from 400A to 4000A, covering light commercial through heavy industrial applications. Both NEMA 1 (indoor) and NEMA 3R (outdoor weather-resistant) enclosures are available.

Yes. All DEI Power switchboards, switchgear, and SES assemblies are UL 891 certified and comply with UBC, CBC, and IBC requirements for all seismic zones. EUSERC-approved configurations are also available for utility service entrance applications. These certifications ensure code compliance across commercial, industrial, and utility projects nationwide.

Most orders ship within 1 business day from DEI Power's Ontario, California facility, with standard delivery in 3–5 business days. Free shipping is included on all orders. In rare cases, up to 5 business days may be required for processing. All assemblies include a 1-year manufacturer warranty covering parts and workmanship.

Yes. DEI Power's in-house manufacturing capability allows assemblies to be configured to specific voltage, amperage, layout, and utility requirements. Service entrance switchgear must be built to approved utility specifications — customers are encouraged to call and speak with a specialist to ensure accurate configuration and receive a project-specific quote before ordering.
