➊ Electric charge
The breaker is remotely closing with charging of closing spring.
If the breaker closing the closing spring is automatically charged
by gear motors.
➋ Electric closing
Remote closing is operated by the closing coil.
➌ Electric trip
Remote trip can be operated by the trip coil or UVT coil.
Main contacts are operated by the energy of the spring mechanism
and closing spring is charged by the motor in the mechanism. Breaker
is closed by closing coil and tripped by trip coil. These operations are
repeated in VCB as shown in the below sequence chart.

Interruption operation
The interruption of vacuum interrupters
Radial magnetic field type contact
The interruption of VCB is carried out by the vacuum interrupters.
Interrupter contacts as a key part made of copper - chromium (CuCr) material with spiral
shape have low contact wear characteristics and withstand voltage is excellent.
Spiral contacts make the arc generated between the surfaces of contacts rotated around the
surface of contact by the induced magnetic field generated due to the spiral contact
structure, which results in preventing local heating, thereby corruption and interrupting
instantaneously.
Direction of
rotating arc
Columnar arc
Current
Arc driving principle in the contacts of
Radial magnetic field
In case of using the flat contact any of the
designs do not reflect on when contacts are
opening the arc with high temperature is
contracted and fixed in the center of the
contacts,Which is called pinch effect. To
prevent the effect two kinds of contact
shapes are designed. One is Axial magnetic
field which spreads the arc before its
contraction, and the other is Radial
magnetic field which permits the
contraction of the arc but makes it rotated
to disperse the energy. Because contracted
arc is shaped like a cylinder it is called
Contracted arc or columnar arc.
Spiral contact structure (Radial magnetic
field), using the force (F = j×B) generated by
the interaction of the radial magnetic field
caused by the current flowing through the
arc between two contacts, disperse the arc
energy evenly on the surface of contact by
rotating the arc that is contracted by the
pinch effect so as to minimize contact
damage.

Vacuum Circuit Breakers
Vacuum interrupters
The vacuum rate within the VI is very high (approximately 5x10-5 Torr) and the spacing between fixed contact
and movable contact is about 6~20mm, depending on the voltage.
The contacts are in a structure that arc can easily be extinguished and the surfaces of the contacts are made of
special alloy (copper-chromium) and the interior is completely sealed to prevent loss of vacuum.
Therefore the wearing of the contacts can be minimized in the event of short-circuit and the arc energy by
overvoltage or switching can be reduced effectively.

Standards and certifications
E2 (List 1 or List3)
E2 (List3) is first proposed in the IEC 62271-100(2008) to improve the efficiency of the interrupting test.
According to it the number of interrupting test T60 is increased instead of fewer number of T10 and T30
compared to the existing List1. List3 compared with the List1 maintains the equivalent of the test but has
severe test conditions because 34% higher arc energy applied to the breaker. List3 is applied to Metasol VCB
series.

UVT Time delay: UDC
• UVT time delay, UDC is to delay the trip signal from UVT.
•Without UDC the breaker will be tripped instantaneously by the trip signal from UVT installed inside of the breaker
even in the the momentary power failure.
• UDC can delay the trip time to avoid this unintended instantaneous trip in the event of such power failure.
• It can be installed on the cradle or inside of the switchgear.
• UDC provides output contacts for indication of trip status due to the UVT coil inside of the breaker.
b contact is closed at normal state and a contact is closed at trip.

Coil Test Unit: CTU
•When no current flows through the coil it gives the test current which does not cause the coil to operate to check
whether the coil is disconnected or not.
- If the test current flows normally: coil normal
- If the test current does not flow through: coil disconnected
※ As it is connected in parallel with the control part of the coil the normal operation of the coil is not affected.
※ Monitoring of the running coils is not possible.
※ One test unit can monitor up to two coils.
1. Input voltage: AC/DC 75V~264V
2. Contact output
1) 2×a contacts for Fail indication and 2×a contacts for Alarm
2) 250Vac/10A Resistive, 30Vdc/10A Resistive
3. Disconnection test cycle is 12 seconds (Test LED blinks)
4. The default operation
If Fail happens (coil disconnected), Fail LED turns on and the Fail contacts become short state.
If Fail happens three times in series, Alarm LED turns on and the Alarm contacts become short state.
In order to clear the Alarm status push up DIP switch on the front and then push down it (Off → On → Off)

Technical data
Standard Use Environment for Metasol VCB
The operation characteristic of Vacuum Circuit Breaker such as insulation and endurance is often influenced
largely by external environment and thus should be applied appropriately with conditions of the place where
it is used taken into consideration.
The following values are the limits have been set in accordance with IEC 62271-100 (IEC 62271-1)
Ambient Temperature
- maximum temperature: +40℃
- 24-hour average maximum temperature: +35℃
- minimum temperature: -5℃
Altitude
- 1000m or less above sea level
Relative Humidity
- 24 hours average value: 95% or less
- One month average: 90% or less
▘If a standard circuit breaker is used in high temperature exceeding 40℃, you are
advised to use it according to the current corrected for each level of ambient
temperature in catalog.
▘If used in conditions of high humidity, the dielectric strength or electric
performance may be degraded.
▘It is highly recommended to use a dust cover or anti-humid agent if it is used in
dusty and humid conditions.
▘Excessive vibration may cause a trip breaker such as connection fault or flaw on
mechanical parts.
▘If it is left ON or OFF for a long time, it is recommended to switch load current on
a regular basis.
▘It is recommend to put it in the sealed protection if corrosive gas is prevalent.

The circuit breaker is designed for use in standard use environment specified in Section 2.1 of
IEC62271-1.
Concerning the special use environments as below the special use conditions are
required to be considered, thus please contact us in advance.
- where altitude and ambient temperature are out of standard use environment.(-40℃)
- where a strong sea breeze blows
- when usually used in a humid place
- where a lot of steam or oil steam exists
- where explosive, flammable and other harmful gases might permeate the breaker
- In a dusty place
- where abnormal vibration or shock exists
- where a lot of ice and snow exist
- other special conditions
Withstand voltage
compensation
according to altitude
If the breaker is used in areas of sea level higher than 1000m the degradation of insulation
performance should be taken into consideration.

Ex) Selecting a breaker to be used in a place of 2500m above sea level with a rated voltage 7.2kV
(correction parameter 1 applied)
- correction parameter at 2500m is 1.2
- c riteria of withstand voltage by rated voltage:
Power Frequency Withstand Voltage (Ud) = 20kV, Impulse Withstand Voltage (Up) = 60kV
- r equirements withstand voltage criteria:
Power Frequency Withstand Voltage (Ud) = 20×1.2 = 24kV, Impulse Withstand Voltage (Up) = 72kV
Therefore rated voltage 12kV breaker shall apply to satisfy the required withstand voltage.
Ex) To apply a breaker with a rated voltage 12kV to the place of 2,500m above sea level
(correction parameter 2 applied)
- correction parameter at 2500m is 0.825
-d
ielectric strength of VCB : Power Frequency Withstand Voltage (Ud) = 28×0.825 = 23.1kV,
Impulse Withstand Voltage (Up) = 75×0.825 = 62kV/1.2×50 ㎲
Therefore above breaker with rated voltage 12kV shall apply to rated voltage system 7.2kV at the altitude.

Vacuum Circuit Breakers
Rated current
compensation in
accordance with
ambient temperature
When normal ambient temperature exceeds the temperature specified in the environment
the following formula help to select the applicable current.
Ia= Ir ( (Θmax - Θa)/Θr)1/2
Ia: allowable continuous current in the actual ambient temperature Θa
Ir: rated current at 40℃ ambient temperature
Θmax: acceptable overall temperature of the hottest spot
Θa: the actual ambient temperature expected at -30℃ and 60℃
Θr: allowable temperature in the hottest place at rated current
Ex) The calculation of the applicable load current value when a breaker with rated current
2000A is used at 55℃ ambient temperature
Ia = 2000×((105-55)/65)1/2 = 2000×0.87 = 1754A
