A Motor Control Centre groups motor starters, overload relays, contactors, and motor protection devices into a single floor-standing assembly. It centralises control of pumps, fans, conveyors, compressors, and other motorised equipment in industrial and infrastructure plants.

Schneider Electric's Okken and Blokset MCC platforms support fixed, withdrawable, and disconnectable starter buckets with TeSys motor protection and Modbus or PROFIBUS communication.

FAQ

Frequently asked questions

What is a Motor Control Centre (MCC)?

An MCC groups motor starters, overload relays, contactors, and motor protection devices into a single floor-standing assembly. It centralises control of pumps, fans, conveyors, compressors, and other motorised equipment in industrial and infrastructure plants.

What starter bucket types and motor protection does NLC's MCC support?

It supports fixed, withdrawable, or disconnectable starter buckets with TeSys motor protection up to 800 A.

Which Schneider Electric platforms are NLC's MCCs built on?

They are built on Schneider Electric's Okken and Blokset MCC platforms, with TeSys motor protection and Modbus or PROFIBUS communication.

What segregation and control configurations are available?

MCCs offer Form 4b segregation for arc-flash containment, variable speed and soft-start configurations, and Modbus, PROFIBUS, and Ethernet/IP communication.

Where are Motor Control Centres typically used?

Typical applications include petrochemical and oil & gas plants, water treatment and pumping stations, manufacturing and process facilities, and data centre cooling and HVAC plants.

Why does the MCC use Form 4b segregation?

Form 4b segregation separates busbars, functional units, and terminals into compartments for arc-flash containment, which improves safety and allows maintenance on one starter without disturbing the others.

Can the MCC include variable speed drives and soft starters?

Yes. The MCC supports variable speed and soft-start configurations alongside direct-on-line starters, all with TeSys motor protection, to suit the motors being controlled.

How do I request a configured MCC from NLC?

Send us your motor schedule and project specifications. Our power engineers will respond with a configured proposal based on the Schneider Electric Okken, Blokset, TeSys, ComPact NS/NSX, and EasyPact CVS ranges.
