Detail Description

Application

KPM6(ABB) series moulded case circuit breaker. It is applicable circuit of AC 50Hz or 60Hz,rated insulation voltage 660V, rated operating voltage under AC660V, 690/250V(DC), rated operting current 1215A-1250A, for distribute energy of electricity and infrequent making and breaking circuit, in normal conditions. The MCCB rated current under 400A they are provided with the function of the protection against overload and short circuit and undervoltage. The MCCB complies with standard of IEC947-2, GB14048.2, GB14048.4 and so on.

Type and meanings

Note:
.No code for distribution breakers; \"2\" represents motor protection circuitbreakers.
.No code for direct handle operation; \"P\" represents electrical operation,and \"Z\"??represents-? rotary-?operated-?handles.
.Rated breaking capacity grade of MCCB: E-Economical type S-Standard type M-High breaking capacity type H-Highest breaking capacity type.

Classification of MCCB
.Installation type of MCCB: MCCB are suitable for vertical or harizontal installation.
.According to use of MCCB: distribution circuit protection type, motor protection type
.According to connection way : front panel connection, back panel connection plug-in connection;
.According to operation way: for direct handle operation for external rotary handle operating, formotor operating;
.According to overload release type: magnetic release (only instantaneous) the modynamic magnetictype (dual), electronical release;
.According to number of poles: two poles, there poles, four poles.
.The neutral poles (N poles) of four poles MCCB has for types:
.Type A: no overload release on N pole, which is making at the time ; not closing and opening with the other three poles.
.Type B: no overload release on N pole, which closing and opening with the other three poles
.Type C: with overload release on N pole, which closing and opening with the other three poles.
.Type D: with overload release on N pole, which making all time; not closing and opening with theother three poles.
.Type E: with a neutral pole interruption protector on N pole that closing or opening with other threepoles.

Main technical Specifications
Motion characteristic

The thermodynamic release of a circuit breaker provides the feature of inverse time-delay, while the magnetic release is the instantaneous operation as shown on table 2(distribution circuit breaker) and table 3 (motor protection circuit breakers).
Rotation handle operated mechanism

The rotation handle operated mechanism used in KPM6 series MCCB ,meet the requirements (drawer chambers, distributor panel and power supply boxes )of set swithgear It can ensures the safety of equipment when the MCCB aare close .i.e it
with panel door with handle in ON position ,may turn the Red release button in
Rotation handle pedestal side
Shown in above fig. Hinge of panel door to handle centre R and breaker cover to cabinet panel H isminimum distances.

Motor operators
Motor operator are used to make or break the MCCB automatically in the distance.

Lock device
.With padlock front panel type is used by MCCB of fumish operating mecha-nism. (Applicable M
CCB type: KPM6-250~JM6-800) (MCCB) is \"OFF\" posi-tion when the locked device operated may avoid making of MCCB. It\'s ration three unit padlock of diameter 6mm (user provide for oneself ). It\'s selectionunder following

.Alt i.e. Alarm contact Sht i.e.Shunt release UVT i.e. Undervoltage release AUX i.e.
Auxilarycontact
.Two auxiliary contact and alarm contact only supply by inm 630A and 800A
Working environment
The MCCB can be reliably operated under the following conditions
1. The altitude not exceeding 2000m;
2. The ambient temperature is from -5 to +40
3. Ambient environment freeing from explosive danger and air or dustwhich may cause corrosion of metal or weakness of insulation;
4. Ambient environment freeing from erosion of rain or snow;
5. Pollution degree 3;6. Installation category III.
