Overview

The MCC room, factory-direct

An MCC container is a purpose-built steel building on an ISO container base that houses motor control centre switchboards, drives and starters, fitted out before it ever reaches site. Motor control centre buildings from SCS are complete steel enclosures: shell, insulation, cooling, cable reticulation and lighting finished on one production line, then delivered to site as ordinary container freight. They sit within our containerised switchrooms and electrical infrastructure range and are built on the same production platform: welded shells, ISO corner castings and factory fit-out before dispatch.

Specifications

MCC Building Specifications

An MCC building is built on a 3 m, 6 m or 12 m ISO container base with double-gasket sealed doors, pressurisation fans and cable management ready for switchboard installation. Cooling is sized to the housed load: ventilators for passive duties, air conditioning with external condensers where drive heat demands it, in N+1 or N+N configurations. Dust exclusion works as a system of gasketed doors, sealed penetrations and positive-pressure fans, rated under IEC 60529, with IP55 and IP56 the category tiers for this enclosure class. Specifications conform to industry standards. Confirm to project requirements.

Scope of Supply

Containerised MCC Buildings

One boundary shapes every MCC project scope-of-supply. SCS builds the containerised MCC building: the sealed, cooled, cable-ready structure that keeps switchgear running. The MCC switchboard inside it is your switchboard builder's scope, designed and certified by the party that assembles it. EPCs, mining operators and plant engineers package containerised motor control centres this way on remote projects: building from the building manufacturer, boards from the board builder, and each certifying its own work.

VSD Housing

VSD & Motor Starter Housing

MCC buildings house variable speed drives, reduced-voltage soft starters, PLCs, remote I/O and power monitoring: equipment specified and supplied through your switchboard builder or integrator, governed at component level by IEC 60947-4-1. The building's job is the environment that equipment needs. Heat rejection is sized against drive losses: a drive-dense room sheds more heat than a plain distribution board. Positive pressurisation keeps dust off electronics between filter changes, and cable zoning separates power and control runs on earthed racking.

Compliance

Compliance & Standards for MCC Buildings

The building fabric is certified for transport under ISO 668, ISO 1496 and the International Convention for Safe Containers. The housed switchboard and the site installation each carry their own compliance pathway, and knowing who certifies what keeps a procurement scope clean. Three parties, three layers. SCS certifies the building it manufactures, on its ISO and CSC transport basis, with Region D cyclonic tie-down engineering the category practice for Australian deployments. The switchboard builder verifies the MCC assembly under IEC 61439-2, the power switchgear and controlgear assembly standard. The installing electrician certifies the fit-out wiring under AS/NZS 3000. Enclosure penetrations keep their IP rating under IEC 60529, and fire-rated door and insulation options are specified per project.

Sizes & Configurations

MCC Building Sizes & Configurations

Containerised MCC buildings come in 10ft, 20ft and 40ft sizes, with custom lengths from 3,000 to 12,000 mm built off the ISO frame. All sizes hold ISO 668 geometry, so the finished building lifts, trucks and ships with standard container handling. Where the duty includes transformation or MV switchgear beyond a motor-control room's scope, containerised substations carry that depth.

3 m (10ft) Unit

Suits a single board and local isolation duty.

6 m (20ft) Unit

The workhorse single-container format.

12 m (40ft) Unit

Carries full switchboard line-ups with internal segregation.

Custom Lengths

3,000 to 12,000 mm built off the ISO frame to the switchboard schedule.

Fitout-Ready Tier

Cable entries, racking and services rough-in complete, ready for switchboard installation.

Fully Fitted Tier

Complete environmental fit-out through to fully fitted configurations, delivered as one freight movement.

Applications

Applications

Containerised MCC buildings run motor loads at mine process plants, water and wastewater treatment works, manufacturing sites and oil and gas facilities, placed hard against the driven equipment. On larger installations the MCC room works alongside containerised control rooms: boards in one building, operators in the other.

FAQ

Frequently Asked Questions

Three questions procurement, engineering and operations teams ask most often about MCC buildings.

What is a motor control centre?

A motor control centre is a switchboard assembly of motor starters, contactors, protection devices and drives that runs a plant's motor loads. It is designed and certified by a switchboard manufacturer. SCS manufactures the containerised building that houses it: the sealed, cooled, cable-ready enclosure the assembly installs into.

What is an MCC building?

An MCC building is a containerised steel enclosure purpose-built to house a motor control centre switchboard: dust-sealed, climate-controlled and fitted with cable management before it leaves the factory. Delivered as one freight movement, the MCC room replaces a site-built structure for motor-heavy plant and relocates when the project moves.

What IP rating does an MCC building need?

Most containerised MCC buildings are specified at IP55 or IP56 under IEC 60529: dust-protected, and sealed against jetted water at increasing severity. The right tier depends on site exposure, washdown practice and the housed equipment's own enclosure ratings. Our compliance guide covers the selection logic.
