Withdrawable Motor Control Switchboard Systems

Withdrawable low-voltage motor control switchboard systems, especially used in panel applications called Motor Control Centers (MCCs), are a reliable and flexible power management solution that ensures energy continuity. The biggest feature of these systems is that each circuit is placed in a separate and individual withdrawable unit. In the event of a failure, the defected withdrawable unit can be quickly removed and replaced with a spare one without the need for repair, ensuring energy continuity. This feature not only guarantees uninterrupted operations but also minimizes downtime and enhances productivity. Withdrawable switchboard systems are widely preferred in sectors where energy continuity is of vital importance, such as petrochemical, metal and mining, cement, paper industry, glass, water treatment plants and power generation facilities.

Advantages

Flexibility of System
Combinable panels suitable for high current distribution and motor control 
Available for back-to-back or face-to-face mounting (main busbar top connection module) 
If rear access is possible, cable connection terminals can be positioned behind the withdrawable units for saving more space
Corner turning module suitable for U or L shaped layouts 
Wider cable connection compartment commonly used by two drawer sections 
Wide range of options such as soft starters, frequency converters, PLC controlled synchronizations and power supply transfer equipment, power factor improvement units, harmonic filtering, etc.
Personnel Security
The withdrawable units, in all sizes, are equipped with mechanical interlocks to protect against operational errors and ensure safe handling. A clear, consistent indicator is provided for all positions of the withdrawable units.

The withdrawable unit can be moved to the "connected" position while the door/cover is closed, without collapsing the ingress protection rating.
Each functional unit is internally segregated.

The enclosure provides a standard ingress protection level of IP31, which can be optionally increased to IP54 for greater protection.

The internal separation complies with the IPXXB standard, ensuring protection against finger contact, even for disconnected units. The units remain protected even when removed.

For all outgoing circuits, the drawer locking mechanism prevents both access and removal when the main circuit breaker is in the "OFF-ON" position.

Motor protection switches and circuit breakers can only be replaced when the withdrawable unit is completely removed.

When the withdrawable unit is removed, contact shutters provide insulation for the distribution busbar.

With the appropriate safety precautions in place, it is safe to work on the output cables even when the busbar is live.
Operational Safety
The vertical distribution busbars are surrounded by double-layer insulation.

Withdrawable unit compartments can be replaced without interrupting operation.

Cable connection to withdrawable units can be done under live conditions.

Optionally, additional insulation of the main busbar conductors can be carried out with thermoplastic material.

The sliding contact structure, which provides separation between the distribution busbar and the withdrawable unit, prevents contact wear or
welding of the contacts to the busbars and ensures the continuity of proper contact even under short circuit conditions.

Ease of Maintenance
By having the double-finger contact design, there is no need for maintenance on the distribution busbar.

Replacement of the double-finger contact holders is a fast and simple process when necessary.
