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.
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.
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.
IEC60947-3：Switch, isolating switch, load switch etc.
