Circuit breakers / Manual motor starters
Type CTI 15

Circuit breakers/Manual motor starters CTI 15
cover the power ranges 0.09 – 7.5 kW

This product range is modular, flexible, and offers
a large selection of clip-on auxiliary functions
and accessories: auxiliary contact blocks, shunt
releases, connection terminal, bus bars and
enclosures.

Features • Short-circuit protection:

An advanced and fast reacting contact system
with arc-control devices give CTI high
short-circuit break capability which makes
them very suitable for the protection of
electrical panels.

• Indicating functions:
– condition (ON or OFF)

• Supply isolation:
– operation switch (manual motor starter)
– isolation switch (with locking device)
– emergency stop switch

Short circuit protection

Short circuit coordination is the connection between
the specifications of the protection devices, such as
fuses, circuit breakers, MCCB and its ability to resist
short circuit.

Short circuit coordination type 1

Test demand
O-t-CO
O = Breaking a short circuiting
CO = Making and breaking a short circuiting
t = Defined pause (3 min)

No damage to equipment or personal injury may occur
in the event of short circuit. However, contactors and
thermal overload relays are not required to remain
functional after short circuit.

coordination type 1.

Short circuit coordination type 2

O-t-CO-t-CO
O = Breaking a short circuiting
CO = Making and breaking a short circuiting
t = Defined pause (3 min)
t = Defined pause (3 min)

No damage to equipment or personal injury may occur
in the event of short circuit. However, light contact
welding is permissible, provided that contacts can be
separated without deformation, using a screwdriver for
example. Contactors and thermal overload relays must
remain completely functional after short circuit.
Typically the short circuit breaking capacity during
operation Ics is in use when a plant is dimensioned
according to coordination type 2.

The prospective short circuit current is the current that
flows during a bolt short circuiting without any short circuit
protection device mounted.

The ultimate short circuit breaking capacity is the maximum
short circuit current specified by the manufacturer that
a circuit breaker can handle under circumstances specified in
IEC 947-2 and in EN 60947-2

The rated service short circuit breaking capacity is
the maximum short circuit current specified by the
manufacturer that a circuit breaker can handle under
circumstances specified in IEC 947-2 and in EN 60947-2

The “r”-current is a short circuit test current. The size of
the “r”-current is determent by the nominal current of the
product. (See below)

Iq –current is the maximum prospective short circuiting
current stated by the manufacturer and often at the value
50 kA.

Indicates full short circuit protection at voltages 250 V, 400 V,
500 V and 690 V.

Let-through graphs for
circuit breaker CTI 15

Maximum let-through energy
Rated voltage 400 – 415 V

A: Max. let-through energy ∫ i2 × dt [103 × A2 × s]
B: Prospective short-circuit current ICC [kA]

The energy graph can be used to assess whether a lead
is correctly protected against the thermal effect of a
short-circuit current.
The graph can be read as follows:
If the expected short-circuit current at the point of
installation is set at 8 kA, and a CTI 15 – 10 A is required,
the let-through energy will be 40000 A2s.

Calculation example:

The following generally applies to leads subject to brief
overload:

2

k x S

t = (

Where t = duration of short-circuit current in seconds
S = cross-section of lead in mm
I = short-circuit current in Aeff
k = a constant which for PVC-insulated Cu wire

)

which gives I2 x t = k2 x S

I

= 115

2

2

Maximum let-through current
Rated voltage 400 – 415 V

A: Max. let-through current ID [kA]
B: Prospective short-circuit current ICC [kA]

The theoretical short-circuit current Icc (prospective
short-circuit current) is limited by CTI 15. Id is the
maximum let-through current (highest momentary
value of the limited short-circuit current). This value
is given in the graph as a function of the prospective
short-circuit current.
The graphs have been plotted for eight different CTI 15
ranges.

Thus, for a 1.5 mm2 PVC-insulated Cu wire,
I² x t = (115 x 1.5)² = 29756 A2s.

From the energy graph it can be seen that with
Icc = 8 kA a CTI 15 with max. range setting = 10 A only
allows about 20000 A2s through and therefore protects
the lead satisfactorily.

Protection of PVC-insulated wires against overload
and short-circuiting, in accordance with IEC 364 and
CENELEC harmonizing documents 384–3 and 384–4.

Overload protection is given by the adjustable thermal
circuit breakers in CTI 15 motor starters. The highest
possible release current is therefore significantly lower
than with overload protection by fuses. The magnetic
trips with fixed setting that rapidly open the main
contacts take over protection in the event of short­circuiting. The low total release time ensures that
heating generated in leads by short-circuiting is limited
to a minimum.
Further information is contained in national regulations.

Tripping characteristic of CTI 15

Protected min. cross-section [mm2]

at 380 / 415 V, 50 Hz

Setting in short-circuit protection application

In many cases, CTI 15 are used exclusively for
short-circuit protection - overload protection being
provided by thermal overload relays, e.g. in multi stage
motors or star-delta starters with heavy start, and/or
in reducing motor lead cross-section. Here, the current
value can be set 20% higher than the operating current
so that only the thermal overload relays release when
overload occurs.

1. Thermal tripping current

The adjustable, current-dependent, delayed bimetal
breakers guarantee motor overload protection.
The graph gives the average value at 20 °C ambient
temperature, from the cold condition. When the unit
has warmed up, the release time is less or equal to the
release time in the cold condition.
The accurate adjustment ensures motor protection
even in the event of phase failure.

Short-circuit protection

A. Tripping time (s)
B: Times the adjustable current I

eF

It has become more and more general to short-circuit­protect panels with circuit breakers rather than fuses.
The clear advantages of “fuse-free” installations are:

- Space saving

- Cut-out in all three phases in the event of short­circuiting.

- No problems with non-convertible fuse types

when exporting electrical equipment.

2. Magnetic tripping current

The electromagnetic, instantaneous high-speed trips
react at a fixed response current. At the highest setting
value this corresponds to 11 times the set current for
CTI 15. At a lower setting it is correspondingly higher.

Danfoss circuit breakers CTI 15 conform to IEC 947-2
and are tested in accordance with EN 60947-2. Because
of their fast reaction times and reliability they are
particularly suitable for the short-circuit protection of
panels.
