Thermal magnetic adjustments and characteristics
Thermal adjustment
Low voltage moulded case circuit breakers have a wide thermal adjustment range, one of the
largest on the market. The rated current ‘I r
’ is continuously adjustable from 63% to 100% of this
nominal current ‘I n
’. There are three main points of calibration marked at 63%, 80% and 100%.
Magnetic adjustment
An adjustable magnetic characteristics allows short-circuit protection to be matched to the
load and supply characteristics, for example motor inrush current or generator short-circuit
current.

Microprocessor based characteristics and adjustments EB2 series
Etibreak 2 MCCBs from 250A to 630A frame sizes are available with
electronic protection units. Current ratings, In, of 40A, 125A, 160A,
250A, 400A and 630A are available. These offer great flexibility as their
characteristics can be set to suit a wide range of application conditions.
Overload protection can be set between 0.4 and 1.0 times In.
Selecting a Preset Characteristic for a 400A Etibreak 2 MCCB with Electronic Protection
Every Etibreak electronic protection unit includes
overload protection (L), delayed short-circuit
protection (S) and instantaneous protection (I) as
standard.

Adjustment dials
The left adjustment dial sets the rated current to
match the conductor rating. The right adjustment
dials select one of six on 630A models preset
characteristics. The effects of the left adjustment
dial (labelled IR(A)), and the right adjustment dial
(labelled Characteristics) are detailed in the tables
shown underneath each time/current graph.

Microprocessor based characteristics and adjustments EB series
Characteristics
In addition to the standard overload and short-circuit protection, there are a number of options available to
meet specific application.

EB 1250 s s s s s s o o
EB1600 s s s s s s o o
s-Standard, o- optional
LEGEND
APPLICATION
LTD Long Time delay - Overload protection, True R.M.S.
STD Short Time delay - Short-circuit protection and selectivity
INST Instataneous - Short-circuit protection, fast reaction
I 2 t RAMP
- Provides easier grading with downstream fuse
Pick-up LED
- Lights on LTD overload, flashes on PTA pick-up
TEST report
- Facility for OCR checker for calibration checking
PTA Pre-trip alarm - Useful for loadshedding application
GFT Ground Fault Trip - Protection against ground faults
Standards Time Current Curves
Each part of the curve can be independently
adjusted. This unique asjustability of LTD, STD and
INST enables the standard microprocesor MCCB to
achieve more than 200,000 permuatations of its
time / current characteristic.
This makes ETIBREAK microprocessor range one of
the most flexible on the market.
The I 2 t RAMP switch, which is provided as standard,
assists in discrimation with downstream fuses. With
the switch off, the STD operates with a definite time
characteristic. With the switch on, the characteristic
shape is changing – cutting off the corner which
poses a potential selectivity problem.

OVERLOAD ADJUSTMENTS
The rated current of the microprocessor
based MCCB is adjusted using two current
multipliers. This proces achieves high
accuracy adjustment from 50-100%.
These are the LTD pickup dial I 1
and the
Base current I o
selector switch.
The current (LTD pickup) is achieved as
follows:
Irated= I n
x I o
x I 1
In total there are 15 possible increments
of adjustment between 50-100% as
shown below.

The PTA (Pre-trip alarm) option continuosly monitores the true r.m.s. value of the
load current. When the load current exceeds the present current value Ip the
pick-up led ‘’flashes’’ to provide a local alarm. If the current continues to exceed
the Ip setting for 40 sec. or more a volt free contact will close to provide a remote
alarm. This volt free contact could also be used to trip non-essential load or start
additional generator capacity. The volt free contact will only reset if the load
current decrease to a value below Ip or the control voltage is interrupted.

• Status indication switches mount in the left side of the MCCB.
General purpose and heavy duty status indication switches cannot
be mixed in the same MCCB. Only one alarm switch can be fitted
to an MCCB.
• Shunt trips and undervoltage trips mount in the right side of the
MCCB.
• It is not possible to install a shunt trip and an undervoltage trip in
an MCCB as they occupy the same location. Undervoltage trips can
provide remote tripping if necessary by wiring a normally closed
contact or pushbutton in series with the protected supply.
• Undervoltage trips with time delays require an external time delay
controller which clips to the side of the MCCB.

External accessories
IZ – Interpole barrier. Installed
between MCCB teminal, which
increases the distance between
poles to reduce the possibility of
creepage.
PRS – Terminal cover. The
terminal covers are applied to
the MCCB to prevent accidental
contact with live parts and
thereby protection against direct
contact.
PRS-ZB – Terminal cover for att.
Busbar. The terminal covers are
applied to the MCCB to prevent
accidental contact with live
parts and thereby protection
against direct contact. The width
is different because of attach
busbar.
SP – Solderless terminal
RO – Operating handle, breaker
mounted. It's used when MCCB
is installed in control centre/
switchboard
RO_P – Operating handle,
panel mounted, variable depth.
This consists of an operating
mechanism mounted on the
breaker, an operating handle
mounted on the panel door and
a square shaft to connect the
mechanism with the handle.
MO – Motor operator. Enabling to switch MCCB ON or OFF remotly.
PR – Door flange. Accessory for mounting on panel door.
ZA – Handle lock. Enables the MCCB to be padlocked in neither the ON or OFF position.
ZB – Attach busbar. Used for easier instalation on busbar systems (widen terminals).
PRO – Handle extension. Used for easier manipulation ON/OFF at bigger MCCB’s.
