When multiple motors need to run together without failure, the quality of the control system determines everything. Autologic Controls designs and manufactures Motor Control Center (MCC) panels built for demanding industrial environments across Ahmedabad, Gujarat, and pan-India projects. Every panel we build is engineered to a specific application — not pulled off a shelf.
What Is an MCC Panel?
An MCC panel — short for Motor Control Center panel — is a centralised electrical control system that manages multiple electric motors from one location. Instead of separate starters for each motor scattered across a facility, an MCC panel brings all motor control, protection, and monitoring into one structured enclosure with a shared power bus.
Each section inside the panel houses a combination starter (motor starter + overload relay + circuit breaker or fuse + disconnect switch), making it possible to isolate, start, stop, or protect individual motors without affecting the rest of the system.
MCC panels handle low-voltage applications — typically 415V, 3-phase, 50Hz — and are designed to be expanded as a facility grows.
MCC vs PCC — what’s the difference? A Motor Control Center (MCC) panel manages motor loads and motor starting circuits. A Power Control Center (PCC) panel manages the incoming HT/LT power distribution before it reaches individual loads. In many plants, a PMCC (Power Motor Control Center) combines both functions into one assembly.
Types of MCC Panels We Manufacture
Fixed-Type MCC Panel All components are permanently mounted inside the panel. Suitable for stable production environments where shutdowns for maintenance are planned. Cost-effective and structurally robust.
Draw-Out Type MCC Panel Individual motor control units can be removed from their slots without switching off the entire panel. Ideal for facilities that cannot afford full shutdowns — common in water treatment, pharmaceuticals, and continuous process plants.
Intelligent MCC Panel (iMCC) Integrates programmable logic controllers (PLC), SCADA communication modules, and digital motor management relays. Enables remote monitoring, energy tracking, fault diagnostics, and predictive maintenance from a central control room or a remote device. Best suited for large manufacturing complexes and automated production lines.
PMCC Panel (Power Motor Control Centre) Combines incoming power distribution (PCC function) with outgoing motor control (MCC function) in a single assembly. Reduces panel room footprint and simplifies wiring for medium-scale plants.
Motor Starting Configurations Available
The right starter type protects a motor during startup and keeps energy consumption in check during operation. We configure MCC panels with:
- DOL (Direct On Line) Starters — For smaller motors where high startup current is acceptable and speed control is not needed.
- Star-Delta Starters — Reduces startup current to approximately one-third. Suitable for motors above 7.5 kW where the load can tolerate a brief torque dip.
- RDOL (Reversible Direct On Line) Starters — Allows the motor to run in both directions. Used in conveyors, hoists, and reversing drives.
- VFD (Variable Frequency Drive) Integrated Starters — Controls motor speed precisely, reduces energy consumption, and eliminates mechanical stress on startup. Used in pumps, fans, compressors, and HVAC systems.
- Soft Starters — Gradual voltage ramp-up that protects mechanical couplings and extends motor life. Common in centrifugal pump applications.

Why Choose Autologic Controls?
Application-First Design We don’t sell a standard product. We engineer each panel around your motor load list, starting current requirements, and control logic — so what arrives at your plant is ready to commission, not to modify.
Customised for Your Plant From feeder layouts and starter configurations to DCS/SCADA communication integration, every element is configured to your specification. Custom enclosure sizes, mounting arrangements, and special voltage requirements are standard practice for us.
Quality That Stays on the Floor All panels go through electrical testing before dispatch: insulation resistance check, continuity verification, and operational testing of each starter section. What we hand over has been verified — not just assembled.
Local Presence, Faster Support Based in Ahmedabad, Gujarat, our team can be on-site for commissioning support, troubleshooting, or retrofits faster than a distant supplier ever could. You’re not waiting on a logistics chain when something needs attention.
Professional Team. Quick Response. High Quality. These aren’t marketing words. They’re how we’ve built relationships with clients across manufacturing, infrastructure, and process industries in Gujarat and beyond.

Frequently Asked Questions
What is an MCC panel used for?
An MCC panel (Motor Control Center panel) centralises the starting, stopping, and protection of multiple electric motors in one location. It replaces individual motor starters distributed across a facility with a structured, safer, and easier-to-maintain system.
What is the difference between DOL and Star-Delta starters in an MCC panel?
A DOL (Direct On Line) starter connects the motor directly to the supply at full voltage causing a high startup current. A Star-Delta starter first starts the motor in star configuration (at reduced voltage) and then switches to delta once speed builds up, reducing startup current by roughly two-thirds. The right choice depends on your motor size and the mechanical load it drives.
Can an MCC panel be integrated with PLC or SCADA systems?
Yes. We design MCC panels with communication modules (Modbus, Profibus, Ethernet/IP) that integrate with PLC systems and SCADA platforms, allowing remote monitoring, automated start/stop sequences, and real-time fault reporting.
What IP rating do your MCC panels carry?
Depending on the application and environment, our panels are available in IP42, IP52, IP54, and IP55 ratings as per IS 13947. Outdoor installations and dusty environments like cement or mining plants typically need IP54 or IP55.
What is the difference between a fixed-type and draw-out type MCC panel?
In a fixed-type panel, each motor control unit is permanently wired into the panel — you need to de-energise the section for maintenance. In a draw-out type, individual units slide out of their position without disconnecting the rest of the panel, enabling maintenance on live systems. Draw-out types are preferred in plants that run continuously.
