Motor Control

The IT. MCC incorporates 24V dc based control circuit design and the most space efficient NEMA electromechanical starter in the industry. Simple and cost competitive Communication options along with the most complete Power Integrity Solutions make the IT. MCC an excellent choice for a variety of applications.

Application Description
Eaton Motor Control Centres are custom-made assemblies of conveniently grouped control equipment primarily used for control of motors and for distribution of power. Motor Control Centres are designed for 3-phase applications up to NEMA Size 7 starters.

Features, Benefits and Functions Structure Design
Eaton Motor Control Centres are 20 inches (508 mm) wide and 90 inches (2286 mm) high with vertical compartments having 72 inches (1829 mm) of unit mounting space in 6-inch (152 mm) increments.

Structure depth is 16 inches (406 mm) or 21-inch (533 mm) deep front mounted only and 21-inch (533 mm) deep for back-to-back mounted units. The unique framed design permits the highest flexibility in component and structure configuration.

Accessibility
All parts and wiring are front asccessible. Terminal blocks are side mounted in each unit. Vertical wireways separate from control units provide safe and convenient access to wiring and conduits without de-energizing any equipment.

Flexibility
Modular, framed design permits structure arrangement to be tailored to exactly meet any control requirements with a minimum of unusable space. Vertical compartments are incremented for maximum space utilization and unit interchangeability. A 6-inch (152 mm) Size 1 starter unit provides users the ability to solve demanding space requirements and still meet all NEMA and CSA standards.

Safety
Design tested at the Eaton power laboratory to assure maximum protection for control equipment. Engineered to minimize hazards to operating personnel.

CSA Listing
Standard structures and units are provided with CSA label.

Options and Accessories
Control and Distribution Equipment Packaging
The IT. MCC provides the most innovative packaged solution for the control and power distribution needs of today’s users. The IT. MCC's structural characteristics allows the user to select a complete package of control and distribution equipment in a minimum amount of space. The ability to package a wide range of solid-state products including SV9000 drives, the Intelligent Technology’s Solid-State Reduced Voltage Starters and PLCs meets the most demanding user process needs. The option to provide high ampacity molded case breakers gives the user the flexibility to minimize switchboard or switchgear structures and thereby saves valuable space and reduces design costs. Other packaged products including automatic transfer switches and panelboards, again reduce space requirements and save time and money on equipment and installation costs.

Product Selection

MCC Operation
The Eaton Canadian MCC product line is headquartered in Airdrie, AB. Airdrie, the most progressive engineering in the industry can custom design motor control for the most demanding applications. Most MCCs can be shipped 6 - 8 weeks after receipt of a released order.

Satellites
One of the most unique aspects of the Eaton MCC operation is the ability to provide customized product to meet delivery requirements through a MCC satellite. There are eight regional satellites located throughout Canada serving key geographic markets. Please contact the satellite in your area to discuss opportunities and MCC support for your specific marketplace.

BID Manager
One of the most exciting new tools developed for the MCC product line is the Bid Manager program. Bid Manager is a PC-based pricing program that is capable of providing complete bills of material, front views and prices for Freedom and IT. MCCs. This program can configure a Motor Control Centre to meet a multitude of specific applications and provide accurate bills of material and front view drawings in a matter of moments. The program operates on a user friendly, Windows- based format that offers the most extensive product selection found in the industry. A complete line of adjustable frequency drives and reduced voltage solid-state control, along with insulated case breakers, high ampacity molded case breakers and automatic transfer switches are featured in the program. Control and distribution product can be packaged in a multitude of variations. Please contact your Eaton sales engineer for more details.
