WMCC
In Motor Control Centers (MCCs), withdrawable unit technology offers numerous advantages, particularly in industries where faults must be rectified without halting the process (e.g., the chemical industry or water treatment plants).
The system features high-safety switching capabilities, allowing for switching operations of up to 630A—even in the event of a short circuit—via the control contacts. In the event of a fault, withdrawable modules can be quickly replaced or added without requiring a system shutdown.
Power transmission within the contact modules is achieved using unencapsulated contacts.
The drawer modules can be inserted and removed. The cabling used in conventional connection systems is not employed in the drawer-based system. It is user-friendly from both an aesthetic and a practical standpoint.
WMCC:
- Installed full-drawout modules can be locked in the “service,” “test,” and “disconnected” positions.
- It is protected against misuse by safety lock mechanisms.
- In standard configurations, draw-out modules are available offering 3- or 4-pole options with ratings of 125A, 315A, and 630A.
- It can offer a more economical and effective solution compared to compact modules.
These panels—used to provide optimal system compensation in shopping malls, industrial facilities, smart buildings, treatment plants, and all areas requiring LV power control—are designed by our specialized team using the E-Plan 5.30 software in accordance with IEC 60617 standards.
Frequently Asked Questions About Drawout MCC Panels (WMCC)
What is WMCC?
WMCC (Withdrawable Motor Control Centre) is a type of panel that utilizes withdrawable unit technology within the motor control center. It offers advantages particularly in industries such as the chemical sector or water treatment plants, where faults must be rectified without halting operations.
What is the difference between WMCC and a standard MCC?
In the WMCC, drawer modules can be inserted and removed, and the cabling found in conventional connection systems is eliminated. This offers a user-friendly design—both visually and practically—and provides a more economical solution compared to compact modules.
How do WMCC panels behave in the event of a short circuit?
It features high-security switching systems; switching up to 630A can be performed via control contacts, even in the event of a short circuit.
Is it necessary to stop the system in the event of a malfunction?
No. In the event of a malfunction, drawer modules can be quickly replaced or added without the need to shut down the system.
In which current ratings are the drawer modules offered?
Draw-out modules are available in standard 3- or 4-pole configurations, offering 125A, 315A, and 630A options.
What safety mechanisms do WMCC panels have?
Installed full-drawout modules can be locked in “service,” “test,” and “disconnected” positions; they are protected against misuse by safety locking mechanisms.
In which sectors are WMCC panels used?
It is used in shopping malls, industrial facilities, smart buildings, treatment plants, and all areas where low-voltage power control is required.
How do I select a PREMIUM-X panel?
Yes. PREMIUM-X panels can be configured specifically for the project based on requirements regarding dimensions, protection class, switchgear layout, cable entry direction, compartmentalization, accessories, and installation. Technical details are determined in accordance with the project’s electrical and mechanical needs.
