4. ELECTRICAL PANEL
Control panel is used to accommodate instruments for the purpose of measurement, monitoring,
protection, detection, control and manage the processes. The panels are located in a control room as
well as a field termed as a local control panel (LCP) for operational convenience.

6. DIFFERENT TYPES OF PANEL
POWER CONTROL CENTER PANEL (PCC PANEL) :
Power Control Center. These are used as power distribution board to
control the power supplied to motors, panels and transformers.
A motor control center is an assembly to control some or all electric motors
in a central location. It consists of multiple enclosed sections having a
common power bus and with each section containing a combination
starter, which in turn consists of motor starter, fuses or circuit breaker, and
power disconnect.
MOTOR CONTROL CENTER PANEL (MCC PANEL) :
7. SWITCHGEAR
In an electric power system, a switchgear is composed of electrical disconnect switches, fuse
and circuit breaker used to control, protect and isolate electrical equipment. Switchgear is used
both to de-energize equipment to allow work to be done and to clear faults downstream. This
type of equipment is directly linked to the reliability of the electricity supply.
8. Circuit Breaker
1250 Amps HT 33 KV Indoor Type Vacuum Circuit
Breaker
The 1250 Amps HT 33 KV Indoor Type Vacuum Circuit Breaker
is designed for high voltage applications up to 33 kilovolts.
It operates using vacuum technology, which ensures efficient
and reliable interruption of electrical currents.
The circuit breaker is suitable for indoor installations, providing
protection for various electrical equipment and systems.
With a current rating of 1250 Amps, it can handle heavy
electrical loads and protect against short circuits and
overloads.
The vacuum technology used in this circuit breaker offers
superior performance compared to traditional circuit breakers,
such as oil or air-based ones.
