Meba Circuit Breaker Electrical Service 3VF2

Meba Circuit Breaker Electrical Service 3VF2

·Brief description
1. Compared with traditional circuit breaker or relevant fuse,MEBA C series circuit breaker has excellent protection performance in smaller space, in maximum range can satisfy rated current and faulty current’s requirement.
2. C series  circuit breaker  can  be used in cascade system,  meet next stage circuit breaker’s limit section capacity select protection req-uirement, save whole system cost.
C series circuit breaker complies with IECZ60947-2 international standard;  also comply with main industrial countries standard.

·Features
1. C series  circuit  breaker  including 7 basic frames, frame current from  100  to  2500A.  Each  frame  has up to  415V 100KA (AC240V 200KA)short circuit breaking capacity multiple choice, more flexibility in design, and save space as well.
2. Actually, using  C series  circuit breaker  can  avoid  in  re-design system.  It  can be used in original  switchboard,  feeder ark, bus duct, equipment control panel,  motor  control  center  substitute of old type circuit  breaker.  At  most situations,  can  adopt  same Connector bar, terminal and shaft structure.
3. Circuit  breaker  stan dard  temperature  is  40  degree,  for other higher  ambient  temperature  situation,  can  use  50  degree  factory finalize type design circuit breaker.
4. C series circuit breaker can be used in DC situation as well, 630A frame  3P  circuit breaker   concatenation  used  in  DC600V  breaking capacity can reach 40KA.

·Most reasonable contact terminal system design
C series circuit breaker flexible and special specific is adopt one of the most reasonable design in circuit breaker history, can assure circuit breaker in high fault current fast and reliable breaking.

·Whole testing process in factory
Each C series circuit breaker steady and reliable quality is acc-ording to a whole testing procedure assurance, each circuit breaker’s same pole has to make two times setting test to verify trip,  operating characteristic and electric circuit contentiously.

·High breaking capacity in smaller space
C circuit breaker in shape and electric function can be interchan-ged with Westinghouse moulded case circuit breaker, this means C series circuit breaker is ideal product after  improve its equipment design.

·Operation structure
1.C  series  circuit breaker adopt in fast-separate  and  fast-close mechanical  operation,  which has free trip function,  assure  circuit breaker in short circuit time can not keep closed.
2. Circuit  breaker’s  trip shaft’s  position and two sides’  windows point its working condition:  ‘witch-on’, ‘reak- brake’ and ‘rip’ If circuit breaker overloading,  short circuit, shunt  or  under voltage or press TEST button makes trip, shaft will slip to ‘rip’ position. At mean while if need  circuit  breaker re-switch on,  it should switch shaft to reset position then break brake.

·Current limit feature
   C series circuit breaker adopts high repulsion contact terminal structure and advantage ARC technology, so it has significant currentlimit function.

·Standard
  IEC60947-1:General rule
IEC60947-2:Circuit breaker
IEC60947-3:Switch, isolating switch, load switch etc.
