Air Circuit Breaker

Meba ACB Breaker L630S

·Brief description
G series moulded case circuit breaker not only has compact volume than normal circuit breaker or fuse, but
also supply more advanced performance. Advantages as following:

■Easy installation accessory

■Easy installation accessory

■20A-2500A can equip with electronic trip

■Built in 20A earth fault protection

· Most reasonable contact terminal system design

Excellent contact terminal design makes G series circuit breaker outstanding performance and high flexibility possible. Our licensed technology adopts speed ’air-blowing’ system, this system adopts high breaking capacity fault current electric power function.

G circuit breaker adopts operation shaft equipment structer, this structer can trip freely when short circuit, shaft can direct definitely trip which caused in short circuit or overload, this fast and reliable operation system improve the safety performance.

·Completely testing before delivery
G circuit breaker’s quality and reliable is assured by completely testing, each pole on circuit breaker will make 2 times setting test to assure trip structure, operation structure and continuously and precision.

·Operating mechanism
1.
G circuit breaker adopts shaft operation feature, this shaft can instruct circuit breaker’s  working condition: ON OFF and PIPPED.

2. When circuit breaker appear overloading, short circuit, shunt or under voltage trip action, shaft will jump to TRIPPED (trip) position, at this time, if need to re-switch on must push shaft to RESET position.

3. On both sides of shaft on EG and RG frame there will have 2 windows, which direct circuit breaker’s  working condition, red, green and white each correspondence  to: On/OFF/TRIPPED.

C Series Moulded Case Circuit Breaker

Meba Low Voltage Moulded case circuit breaker HMDLB65k

·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.
