Designed for demanding industrial applications
Motor control / Power distributionMore than panels.
Control of the entire system.
Explore motor control, engineered electrical panels, and integrated automation solutions backed by the same controls engineering and technical coordination.

MC-PLEX® Motor Control Complex
SSAC’s modular motor control architecture brings motor and VFD control, electrical protection, distribution, networking, and operational visibility into one coordinated system.

PLC, HMI & SCADA Integration
Programming, operator interfaces, alarm management, network integration, testing, startup and commissioning to connect equipment with the people who operate it.
Discuss automation needs →
From the first drawing to final commissioning.
When engineering, fabrication, programming, and startup need to work together, fragmented handoffs can create complexity. SSAC brings these disciplines into a coordinated controls project.
When timing matters, design matters.
See how Solid State Automation & Controls worked with Rittal to rethink the motor control architecture for a facility facing a long traditional MCC lead time.
Project-specific case study. Results do not represent a guaranteed lead time for other projects.
Read the published case study ↗Automation that fits the way your facility runs.
Whether you are expanding a production line, upgrading an aging PLC platform, specifying a new motor control system, or restoring visibility across an operation, the engineering must match the process, the equipment, and the schedule.
A better RFQ starts with the right details.
Industrial control panel and motor control center specifications can vary substantially. Share the information you already have; SSAC can help clarify the technical scope.
The application
Facility use, process description, current equipment, motor or VFD requirements, production objectives and operating constraints.
The electrical scope
Available single-line diagrams, voltage, current, I/O counts, panel environment, enclosure requirements and relevant standards.
The controls platform
Existing or preferred PLC, HMI and SCADA software, network protocols, interface needs, alarms and commissioning expectations.
The project schedule
Required delivery or startup date, outage window, site location, installation constraints and any available engineering drawings.
Have a hazardous-area requirement? Include the area classification and applicable specifications. Panel suitability and certification must be confirmed for the final configuration.

Answers to common questions about Solid State Automation & Controls, MC-PLEX®, industrial control panels and the RFQ process.
What does Solid State Automation & Controls manufacture?
SSAC engineers and builds MC-PLEX® motor control complexes, custom industrial and PLC control panels, HMI enclosures and related controls systems. It also provides controls integration, software retrofits, programming and commissioning services.
How is MC-PLEX® different from a traditional MCC?
MC-PLEX® is SSAC’s modular motor control architecture, designed to coordinate motor/VFD control, distribution, protection and operational visibility. The proper configuration and advantages depend on the equipment, electrical scope and facility requirements.
Can SSAC build UL 508A and UL 698A control panels?
SSAC reports UL 508A and UL 698A panel fabrication capabilities, as well as UL 891 switchboard capability. The applicable listing or certification for an individual assembly should be confirmed during engineering and quoting.
Does SSAC handle PLC, HMI and SCADA modernization?
Yes. Its controls engineering services include PLC programming, HMI/SCADA integration, industrial communications, hardware and software upgrades, commissioning and technical support. Share your current platform and modernization goals to begin scoping.
Does the 50-week case study mean every project ships that quickly?
No. The 50-week reduction was achieved in one documented motor control project compared with its original conventional MCC schedule. Actual delivery times depend on design, approvals, materials, scope and production capacity.
