Draw-Out Motor Control System
Thursday, November 20, 2025
Motors are the heart of industrial operations. Ensuring their safe, uninterrupted, and efficient operation is critical for business continuity. We provide solutions to meet this need with PDS Draw-Out MCC systems.
Business Continuity
- The biggest advantage of the Draw-Out MCC is that maintenance can be performed without shutting down the system.
- When a fault occurs in a motor circuit, only the relevant drawer is isolated and removed, while the other motors continue to operate.
- This ensures uninterrupted production and prevents losses.
- Reduced unplanned downtime → increases efficiency and provides significant cost savings.
Safety
- Each drawer is independently isolated.
- Personnel do not come into contact with other circuits during maintenance or intervention.
- Designed in compliance with international IEC 61439-2 standards.
- Result: operator safety is maximized.
Flexibility and Modularity
- As the business grows, new motors may need to be added.
- The modular structure of the Draw-Out MCC allows easy expansion.
- Different power requirements can be quickly accommodated by changing the drawer.
- This ensures that your investment is future-proof.
Easy Maintenance
- Drawers are pre-tested, independent units.
- A faulty drawer can be replaced within minutes.
- Reduced maintenance time increases labor efficiency and lowers costs.
- With a spare drawer, the motor circuit can be quickly reactivated.
