Molded Case Circuit Breakers - BW Series MCCB
 

Molded Case Circuit Breakers
- FUJI BW Series (100/160/250AF) MCCB

We’ve expanded our MCCB lineup with the addition of models with global frame sizes of 160AF and 250AF.

MCCB production started in 1968, and the hard earned expertise gained over the years has established global reputation for high quality. MCCBs are used in many different types of electrical distribution and control systems.The most important requirement is to provide dependable, safe protection of load devices in the event of a short-circuit. Making use of related technologies, Fuji Electric FA components & Systems Co.,Ltd. has developed a global frame size lineup of MCCBs. This time we provide a three-fold concept for compact, cassette-type, BW series MCCBs, resulting in a global series.

 
     
  Compact
We’ve applied high-performance technology to achieve 100AF to 250AF models with a uniform depth of 60 mm.
Compact design has been realized for the MCCB family series from 30AF to 800AF.
We’ve achieved a Ics of 50% Icu.
 
     
  Cassette
All accessories can be assembled by the user.
Quickly adaptable to the many onsite changes in specifications.
 
     
  Global
Introducing new frame sizes: 160AF and 250AF
Fully compliant with IEC standards while providing the required safety.
 
     
 
Enhanced Breaking Technology

“BW Series” circuit breaker emploies an unique and ideal breaking mechanism that give you enhanced breaking capability from the beginning to completion of interruption.
Achieve high speed contact opening according to increasing electromagnetic force to opening direction by joint using of flat stationary contact and magnetic yoke.
Accelerate movable contact speed by arcing gas generated from special resin located closely to movable contact.
Drastically reducing clearing I²t according to increasing arc driving force to arc chamber by magnetic yoke to rise arc voltage rapidly.
