the Industry since 1997. We design build and supply a vast array of Electronic Protection Relays and our vision is to become the best supplier
for Motor protection and Motor management for its customers nationwide.
We will continue to offer the best technology at most competetive prices to our users to help them stay abreast with the most demanding and
competetive enviornments globally. We will also strive to attain service and distribution levels for our Protection Relays that will set a new
benchmark for the customers satisfaction.
As always our focus will be to assist our customers in acheiving their goals of safely securing the finite natural resources before it’s too late
and help save on precious natural reserves and expensive down times in their respective industries thereby reducing our carbon footprints for
our next generations.
Our products always have and will be designed to last very long and continuously work to protect your energy, materials & manpower costs.
Keeping in mind our local working conditions at various locations across the country the products we will supply to our customers will be

2008 we gaurantee the highest quality products and services. Manufactured under stringent Quality procedures all our products conform to
latest relevant international standards.
OVERVIEW
The 3 Phase Electric Motor, is the workhorse of every industry and failure to notice unwarranted conditions can lead to disastrous results. The
entire range of Electronic Motor Protection Relays offered by CONCORD are chosen carefully based on our experience and understanding of
the needs of different users. All models offered by us are unique and different from each other in terms of Protections offered and principle of
operation so that the user has the unique advantage of choosing the right product for their applications.
By choosing the right protection device, users can ensure longer life from their motors and avoid untimely failures resulting in loss of
manpower, materials and natural resources like copper for rewinding procedures. Despite having conventional electro mechanical products
for motor protection, it is a known fact that notor failures are quite common and lead to execcesive costs, downtime and loss of materials in
process. which are far greater than the cost of the motor and allied protection equipment.
In the kind of conditions that prevail in our industry, it is not uncommon to have Over or Under Voltage, Loss of one Phase, Change of Phase
Sequence, Bearing failures due to high levels of dust and pollution, Over heating, Jamming or stalling of rotors, Very frequent start stop
operation of motors, Initial High Torque requirements etc All of these conditions lead to premature motor failures and fault diagnosis is
seemingly not possible after the motor has failed, because most of the times the failed part is a result of another unattended problem which
was not addressed on time.
As there is not much data to confirm exact cause of Motor failures, it makes it even more imperative to move from Reactive and Preventive
maintenence to Diagnostic and Predictive maintenence to save on valuable resources and time. Here is why Electronic Motor Protection
Relays are more useful to the industry hereby saving precious resources, time and money.

O-TIME ( Operating Time on Overload)
TEST FUNCTION
Looping Option
The D-Time is the time taken by the motor before it reaches it’s
normal running current. During start the motor draws much higher
levels of current and the D-Time setting is to ensure that the EOCR
does not cause any nuiscance trippings before this set time has
elapsed. After the D-Time setting is over the relay monitors the
normal running currents.
O-Time is the operating time in the event of overload. When motor
current exceeds the desired set current value, the EOCR detects
the increase and trips the motor within the set O-Time preventing
excess heating and long periods of overload.
The TEST function facility on the front face of the relay is provided
to check the health status of the relay without electrically
energizing the relay. On pressing the TEST button the internal relay
will trip after the D-Time + O-Time settings have elapsed. After
using this test facility, the RESET button has to be pressed to
operate the relay
Looping option is required in case the amount of current
measurement is desired to be more accurate and precise. The wire
from the main line when passing through the Internal EOCR CT is
looped one or more times depending upon the current range of the
relay to suit the application.
RESET FUNCTION
EXTERNAL CT OPTION
By pressing the RESET button or disconnecting the electrical
supply will trip the relay immediately. Once the relay has tripped
due to any Over Load or any other fault, the relay has to be reset to
start the motor again.
By usinf External CT’s with secondary rating of 5A the EOCR can be
ised to monitor and protect motors with
normal running currents of upto 600A.
This is used with an 05 Type relay with
current setting range of 0.5 - 6A. In
Digital models the display current
values are selectable as desired.

CONCORDELECTRONIC PROTECTION RELAYS WITH DIGITAL DISPLAY AND FAULT DIAGNOSIS
INTRODUCTION
The complete range of Digital Motor Protection Relays from
CONCORD are designed for use with 3 Phase motors. The
inherent design features are built to make Motor protection far
easier and more accurate. The Digital Diplay works as an Ammeter
dsiplaying the actual motor current and also acts as Diagnostic
Display highlighting the various causes of motor tripping to assist
the user in trouble shooting and drastic reduction in downtime
whenever an Electrical fault occurs in the system.
These relays are built using a MCU - Microprocessor Control Unit
and are suitable for use for a very wide range of appli cations and
motor sizes. The Test function button enables the user to use the
same model for motor sizes ranging from 0.5A - 600A. There by
resulting in drastic reducion of inventories.
Insensitive to the Ambient temperatures and designed to suit local
conditions these Relays offer you Total Motor Protection and
gaurantee peace of mind.
