General Information
Sigma MCBs are such devices that protect their connected circuits against short circuit and overload.
Sigma MCBs produced as 3 kA, 4.5 kA, 6 kA, 10 kA and 16kA according to the EN 60898-1, EN 60947-2 and VDE 0660.
They are also conforming to the Low Voltage Directive (LVD) 73/23/EEC.

Installation
Up to 25 mm2 cable can be connected to the sigma MCBs, which are designed
to be easily mounted on to the 35 mm DIN rail according to EN 50022. Besides,
connection with collective MCB Bus bar is possible. Maximum torque applied
for connection screws is 2 Nm. Higher torque may damage to the screws or
terminal connections.
Although Sigma MCBs have availability to make energy entrance from both
upper side and under side, it is recommended to make from upper side.
Connection Terminals own IP20 protection degree according to the EN60529.
The Design that has IP20 protection degree
properties for safe to touch.
Sealable properties
DIN Rail Specifications should be suitable according to EN50022.
Normal Service Conditions
Sigma MCBs are designed to operate at ambient temperatures between -5 oC and +40 oC. The calibration temperature is 30 oC. If ambient temperature value
is different than 30 oC, please use below table to compansate tripping time. The upper limit for relative humidity is 50% at a maximum temperature of +40 oC,
although the breakers can operate at higher relative humidities for lower temperatures (e.g.: a relative humidity of the 90% at +20 oC ambient temperature
would be acceptable).
Sigma MCB specification throughout this catalogue are for installations where the altitude does not exceed 2000m above sea level. For installations above
at higher altitudues, it is necessary to take into account the reduction of the dielectric strength and of the cooling effect of the air. The ambient temperature
during transport and storage must not exceed the interval between -40 oC and +55 oC. For short periods not exceeding 24 hour up to +70 oC can be reached
with a relative humidity of 30%. During this period it is important to avoid water condensation in side the breakers, otherwise, oxidation and stain spots might
appear affecting thus the normal operation of the breaker.

Thermal Tripping Conditions
MINIATURE
CIRCUIT BREAKERS
MCB
Protection Of The DC Circuits
The thermal characteristics for Sigma MCBs are unaffected by the type of current applied, that is either direct current or alternating current. The
magnetic trip value increases by 40%. For example, in the case of a breaker of tripping characteristics B and 10A rated current, its magnetic tripping
value will be between 30A and 50A in alternating current. The magnetic tripping value for the same breaker in direct current will be between 42.4A
and 70.7A
For DC service, the MCBs full rated breaking capacity can be achieved without any reduction in performance by connecting protected poles in series.
For values up to 48V=1 protected pole can be used unpaired of the breaking capacity value. Between 48 and 110V=2 protected poles series connected
can be used without reduction in the breaking capacity. Between 110 and 150V=, 3 protected poles series connected must be used, and 4 poles up
to 200V=

Influence Of Non-Standard Frequencies
For operational frequencies greater than 50/60Hz, the effect of these non-standard frequencies must be taken into consideration. Thermal characteristics are independent from variation in frequency. Magnetic tripping values are directly affected by frequency. As a reference, for frequencies of 100, 200,
300 and 400Hz, the values at which the magnetic tripping occurs become increased in a 10, 20, 30 and 40% respectively.

Protection Of Motors
The protection of motors against the effects of an internal short circuit must be ensured, allowing at the same time the presence of short duration
overcurrents (starting) without causing tripping of the protection element.
This element must also ensure protection of the line, of the contactor and of the thermal relay associated to the motor.

Protection Of The Lighting Circuits
When choosing the MBCs for protection of lighting circuits, it should be considered the power of the lamp, kind of the lamp, number of lamps and high
peak currents when the lamps are energized.
In the lighting circuits consisted of Sodium and Mercury vapor discharge lamps,the peak currents may occur up to 25 times of the rated current at the first
3 ms. Following this, 7 times of the rated current may be drawn within 2 seconds.
In the lighting circuits,inwhich there is electronic ballast worked with high frequency ,the peak currents may occur up to 25 times of the rated current at
the first 250 - 300 μs.
For these reasons, the MCBs are to be selected according to the type of lamps and their endurance against peak currents, so generally C type MCBs are
used in the lighting circuits.
But because of the cable resistance between the lamp and MCB, The value of peak current is limited to an inferior value depending on the distance.

It is possible to make tripping and signalling remotely to the Sigma 6 kA and 10 kA MCBs by adding shunt trip and fault signal contact.
Fault signal contact are mounted to the left side of the surface of the MCBs or Shunt
Trip and when the MCBs are tripped because of the overload or short circuit, the
contacts change the position however when the MCBs open or close the circuit by
manually, the contacts do not change the position.
