Introduction
MOTOR CONTROL CENTRE (MCC)
A Motor Control Center is a modular cabinet
system designed for powering and controlling
motors in a factory thereby assuring total flexibility
and operator safety. A typical MCC cabinet is a
NEMA 12/IP-55 enclosure with a number of small doors
arranged in rows and columns along the front and
flat, mostly featureless back and sides. Behind
each door is a unit which connects the electrical
devices inside to the electrical bus bars behind it.
An MCC with only one column of buckets is called
a single-section MCC. MCCs are very common sights
in factories with heavy machinery, although the purpose
they serve is changing. MCC is capable to feed larger
loads and come with multiple power stabs, to support
high capacity industrial motors. The MCC units include:
? Full voltage non-reversing and full voltage reversing
starters
? AC variable frequency drives
? PLC I/O chassis
? Solid-state motor controllers
? Lighting boards
? Transformers
? Analog or digital metering
? Feeder circuit breakers
? Feeder fusible disconnects
POWER CONTROL CENTRE (PCC)
PCC receives power either from Electricity board or
captive power system and to distribute them to MCCS,
PDBS, LDBS etc. The PCC's are carefully designed, wired,
tested and factory assembled with electrical equipment
installed inside totally as per customer requirements.
Power Control Centers offer customized solution to save
costs not only on installations but also on equipment
storage, handling, and field testing. Power Control Centers
are modeled to house items such as:

Construction features
Pyrotech MCCs are unique combination of innovative
accessories, perfect workmanship. This means superior
aesthetic looking, trouble free and easy maintenance
control centres in accordance to International Standards
that is IEC-60439-1. Panels are sleek & aesthetics is
perfectly compartmentalized section which are made
standardized in design with proper compartment/trolley
sizing and bus bar arrangements. Pyrotech MCCs
are single front as well as double front. Our MCC
design is such that the MCC and busbar can be
extended on either side. There is provision for
running control bus bar throughout the length of
MCC. All the compartment trolleys are earthed
through scrapping earthing arrangement provided on
the trolley and panel connected to earth bus. Auxiliary
doors are provided for control and indicating
instruments on the trolley. MCCs are made in welded
construction system to ensure rigidity throughout the
section.
1)Size -
Standard height of out MCC is 2400mm
including base frame. The maximum
operating height is 1800mm.

Main Parts and Accessories
1)Trolleys - The trolleys are designed with great
precision to avoid any mismatch of draw out
contacts, power as well as control SIC
contacts. The trolleys are having three
distinct positions, Isolated, Test, Service.
Standard Trolley size - 300mm, 375mm,
450mm, 600mm, 750mm and 900mm. All
similar size trolleys are interchangeable.
·Drawout Contacts : silver plated Copper
(tested for 50KA as per IS 8623/IEC 439)
·Power & Control Contacts : silver plated Copper (tested for 50KA as per IS 8623/IEC 439)
·Earthing : Provided by Scrapping Earth Assembly.
·Trolley Movement : On telescopic rail through cranking mechanism.

2)BusBars - Our bus bar design is calculated to
withstand the short time current and the
busbar sizing also is done accordingly. Bus
bar can be either aluminum E91E or
electrolytic grade copper as per customer
requirement. Bus bars are fully shrouded
and the draw out fixed contacts are
shrouded by automatic shutters. Once the
trolley is drawn out, the busbar will be fully
shrouded and thus avoid any accidental
contact with live busbar. The horizontal bus
bar chamber height is 300mm which is fully
isolated from compartments. We use sturdy
silver plated draw out contacts.

FEATURES
The modular designed satisfies the ever-increasing
demand for high performance, high reliability, safe
operation and versatility required in industrial facilities.
Some of the important Features are
(1) MODULAR CONSTRUCTION: Single and/or double
(back to back) front construction. Accessible from front
to the compartment for the modules and cabling way.

ADVANTAGES OF DRAW OUT MCC ON NON DRAWOUT MCC
PARAMETERS
Interchangeability
DRAW OUT MCC
In case of Fault, no Plant shut down is required.
Rack out faulty trolley and insert standby trolley.
The plant remains in running condition while fault
shooting.
Safety
100% Safety
Maintenance Time Zero Down Time
Manufacturing Time Parallel Operation In Production.
Risk of Accident
Production Time
Cost
NON DRAW OUT MCC
In case of fault, plant has to be shut down for
fault shooting until the fault is rectified.
Inadequate Safety
High Maintenance Time
Sequential Operation In Production
Person need not do the maintenance within the
MCC, as the trolley can be racked out and do the
maintenance elsewhere. And all live parts are fully
shrouded; hence the possibility of accidental
approach to the live part even after racking out
Person has to do the maintenance within the
MCC and the chances of accidental approach
to the live part are high.
The design of structure, trolley and draw out
component are standardized, it is Possible to pre
fabricate and keep them in stock. Also Pre
harnessing of wire can be done.
Since the design is non standardized the MCC
to be made as per the requirement.
