OVERCURRENT RELEASES
3P
The electronic overcurrent release consists of a separate and
interchangeable unit, which is supplied with the BL1000SE...
switching unit. By exchanging the overcurrent release, the
range of the circuit breaker’s rated current can be easily
changed. Releases for the BL1000SE305 switching unit are
produced in four current ranges In = 315, 630, 800 and
1000 A. The releases, including their adjustment, cover rated
currents ranging from 125 to 1000 A.
Depending upon the needs for adjusting the release’s tripping
characteristic to the protected device and to the variability
of the characteristic with regard to selectivity, the following
release devices are available:
„ DTV3
They have one type of characteristic with adjustable Ir and Irm.
„ MTV8
They have more kinds of characteristics with adjustable Ir, tr
and Irm.
„ U001
They have universal characteristic, with the greatest
variability in adjustment: Ir, tr, Irmv, tv and Irm.
„ DTV3, MTV8, U001
Proper functioning of releases does not depend on the form
of current in the power circuit. The function of the release is
supported by a microprocessor, which processes a sampled
signal of the power circuit and recalculates it to obtain an rms
value. Therefore, digital releases are suitable for protecting
circuits where the sinusoidal current is distorted by high
harmonics (e.g. circuits with controlled rectifiers, power factor
compensators, pulse loading, and the like).
All the releases protect a circuit against short-circuiting and
overloading. Setting of selective cascading of circuit breakers is
especially enabled by the U001 release. Tripping characteristic
of the releases is independent of the ambient temperature.
The release is affixed to the switching unit by two bolts. The
translucent cover over the adjustment controls can be sealed.
Tripping characteristic adjustment for DTV3 and MTV8
releases
The tripping characteristic of overcurrent releases is defined by
standard EN 947-2. The characteristic is adjusted in two zones
using latched switches on the overcurrent release unit:
L - is a zone of low overcurrents and includes the area of
thermal protection.
I - is a zone of high overcurrents and includes protection
against ultimate short-circuit currents. For MTV8 releases,
the time delay can be set at 0 or 50 ms.
DTV3
The Ir switch is used to adjust the circuit breaker’s rated current.
The characteristic is moved on the current axis. By means of its
internal circuitry, the release is set to one type of characteristic.
„ The dependent release MTV8 is adjusted using two switches,
Ir and tr. The first (Ir) switch is used to adjust the circuit breaker’s
rated current. The characteristic is moved on the current axis. By
turning the other switch (tr), the time is adjusted after which the
circuit breaker will trip while passing through 7.2 Ir. The tripping
characteristic thus moves on the time axis. Using the tr switch, it
is possible to set a total of 8 characteristics. Four characteristics are
available for motors protection. Breaking times correspond with
the release class 10 A, 10, 20, 30. By changing tr, it is possible to
select the characteristic according to the required motor starting
(light, medium, heavy or very heavy starting). For protecting
transformers and lines, 4 characteristics can be set. It is not
possible to turn the device back on right after the dependent
release has been actuated and circuit breaker tripped. The release
must be allowed to cool off, because it has a thermal memory. The
memory can be disabled by turning the “restart” switch from the
normal “Tt” position to the “T0” position. The dependent release
remains active, and only its thermal memory is inactivated.
Switching off the thermal memory should be used only in welljustified cases, and with the knowledge that there could be rising
temperature in the protected device with repeated tripping.
2. Independent instantaneous release (short-circuit trip) I
The independent instantaneous release in designs DTV3 and MTV8
is adjusted using one switch, Irm. The Irm switch is used for setting up
the short-circuit current that, upon its being reached or exceeded,
causes instantaneous tripping of the circuit breaker. Regulation
of the short-circuit release takes in settings for the characteristic
appropriate for protecting lines and motors. The wave form of the
tripping characteristic is adjusted using latched switches on the
release’s front panel according to the needs of the protected device.
A visual demonstration on setting the tripping characteristic can be
found in the SICHR program (see www.oez.com).
Tripping characteristics of DTV3 and MTV8 releases
with load
The tripping characteristic from the cold state indicates the
tripping times during which it is assumed that, up to the moment
when an overcurrent develops, no current is flowing through the
circuit breaker. The tripping characteristic tripped from warm
state indicates the tripping times during which it is assumed
that, before the moment when an overcurrent develops, current
is flowing through the circuit breaker. Characteristics of electronic
releases are independent of the ambient temperature and are

plotted in a cold state. Digital releases enable simulation of a
release in warm state. The tripping times become shorter in a
steady state, as shown in the following graph. The steady state
is a period during which the characteristic does not change. If
the circuit breaker is loaded with a reduced current for at least 30
minutes, the tripping times will be cut by a half. If the load is less
than 70% of Ir , the tripping time does not become shorter.

Thermal standstill time of the characteristics
For all kinds of characteristics tr, the thermal standstill time
for MTV8 and DTV3 releases is tu ≥ 30 min.
During this time, the short-circuit tripping time tv is cut short
from the cold-state characteristic by the coefficient k.
The real tripping time is ts = k . tv

The tripping characteristic of overcurrent releases is defined by
standard EN 60 947-2. The characteristic is adjusted in three
zones using latched switches on the overcurrent release unit:
L - is a zone of low overcurrents and includes the area of
thermal protection.
S - is a zone of medium overcurrents and includes longdistance short-circuit protection for lines. Intentional delay
in tripping of these low short-circuit currents can be used to
achieve selectivity of protective devices. This type of delay
can be set only in self-contained releases (full version).
I -is a zone of high overcurrents and includes protection
against ultimate short-circuit circuits without time delay.
I2t - Characteristic setting in the ON position represents a
constant value of energy passed through. If fuses are used
as protective elements for outgoing branch feeders, it is
possible to adjust the selective part of the characteristics to
better suit the shape of the fuse characteristics.
1. Dependent release (thermal) L
„ The dependent release U001 is adjusted using two
switches, Ir and tr. Using the first switch, Ir, the circuit breaker’s
rated current is adjusted. The characteristic is moved on the
current axis. Turning the second switch, tr, adjusts the time
after which the circuit breaker will trip while passing through
7.2 Ir. The tripping characteristic thus moves on the time axis.
Using the tr switch a total of 8 characteristics can be set.
Breaking times correspond with the release class 10 A, 10,
20, 30. It is not possible to turn the device back on right after
the dependent release has been actuated and circuit breaker
tripped. The release must be allowed to cool off, because it
has a thermal memory.
The memory can be disabled by turning the “restart” switch
from the normal“Tt”position to the“T0”position. The dependent
release remains active, and only its thermal memory is
inactivated. Switching off the thermal memory should be

used only in well-justified cases, and with the knowledge that
there could be rising temperature in the protected device with
repeated tripping.
2. Delayed independent release S
The delayed independent release has the function of a
delayed short-circuit release. It is used to set up a selective
cascade of circuit breakers. It is set up using specifications Irmv
and tv.
Irmv is an n-multiple of current Ir (Irmv = n × Ir). It is a shortcircuit current that, within the span of Irmv to Irm, will trip
the circuit breaker with delay tv, where tv is a delay set up
for switching off the release.
The delayed independent release actuates the circuit breaker
if the current in the circuit reaches at least the preset nmultiple and lasts at least the preset delay time tv.
The independent release can be disabled by setting the
parameter n (Irmv = n × Ir) into the ∞ position. Parameter tv
can be set to values with respect to the energy that passed
through l2t (switch position l2t on). The preset time values are
then applicable for currents more than 10x current Ir. Tripping
times of k-multiples of Ir for k < 10 are defined as follows:
Tripping time shortening with load
T
I r [%]
T – When tripping from the release’s “warm” state, the tripping
time of the characteristic is cut short during the standstill time
tu by coefficient k.
Thermal standstill time of the characteristics
For all kinds of characteristics tr the thermal standstill period for
U001 releases is tu ≥ 30 min. During this time, the short-circuit
tripping time tv is cut short from the cold-state characteristic
by the coefficient k.
The real tripping time is ts = k . tv
3. Independent instantaneous release I
The independent instantaneous release has the function of
a short-circuit release. It is set up only on parameter Irm. Irm is
short-circuit current that, upon its being reached or exceeded,
causes the circuit breaker instantaneously to switch off. It is set
up directly in kA on the release. The wave form of the tripping
characteristic is adjusted using latched switches on the release’s
front panel according to the needs of the protected device. A
visual demonstration on setting the tripping characteristic can
be found in the SICHR program (see www.oez.com).
Tripping characteristic U001 release with load
The tripping characteristic from the cold state indicates the
tripping times during which it is assumed that, up to the
moment when an overcurrent develops, no current is flowing
through the circuit breaker. The tripping characteristic tripped
from warm state indicates the tripping times during which
it is assumed that, before the moment when an overcurrent
develops, current is flowing through the circuit breaker.
Characteristics of electronic releases are independent of the
ambient temperature and are plotted in a cold state. Digital
releases enable simulation of a release in warm state. The
tripping times become shorter in a steady state, as shown
in the following graph. The steady state is a period during
which the characteristic does not change. If the circuit breaker
is loaded with a reduced current for at least 30 minutes, the
tripping times will be cut by a half. If the load is less than 70%
of Ir , the tripping time does not become shorter.
Example
The shortening constant can be read from the graph. With steady
current 85% of Ir the real tripping time will be shortened to:

Description
The SE-BL-J...-DTV3 release is intended only for the BL1000SE...
switching unit. Operation of the release is controlled by
a microprocessor. The release is outfitted with a thermal
memory that can be disabled by turning the switch on the
front panel from position T(t) to position T(0). After disabling
the thermal memory, the thermal release remains active.
A practical advantage of the release is a specially designed
tripping characteristic that provides for optimal exploitation
of transformers up to 1.5 In.
Another advantage of this release is the simple adjustment
of the tripping characteristic. Set-up includes only the rated
current in a range of 0.4 to 1.0 of In and the short-circuit tripping
level. The reaching of 80% and 110% of Ir is indicated by LED
diodes on the front panel denoted as I > 80% and I > 110% of
Ir. On the lower part of the release cover are four photocells for
communicating with the SB-BL-0002 signalling unit.

Description
The SE-BL-J...-MTV8 release is intended only for the
BL1000SE... switching unit. The operation of the release is
controlled by a microprocessor. The release is equipped with
a thermal memory that can be disabled by turning a switch
on the front panel from position T(t) to position T(0). After
disabling the thermal memory, the thermal release remains
active.

Another parameter for adjusting the release is rated current,
which is adjusted in a range of 0.4 to 1.0 of In and the shortcircuit tripping level, for which it is possible to set the delay
at 0 or 50 ms. The reaching of 80% and 110% of Ir is indicated
by LED diodes on the front panel denoted as I > 80% of Ir
and I > 110% of Ir. On the lower part of the release cover
are four photocells for communicating with the SB-BL-0002
signalling unit.

A practical advantage of the release is a specially designed
tripping characteristic that provides for optimal exploitation
of transformers up to 1.5 In. It is possible to set a total of 8
characteristics on the release. From these, in mode “M” there
are 4 characteristics for motors protection and another 4
characteristics in mode “TV” for protecting transformers and
lines. The shape of each characteristic can be changed using
a selector switch.
When one or two phases fail, in the M-characteristic mode,
the switch will open with a 4 s delay (so-called undercurrent
release).
