Rating: upto 36kV, 2500A, 31.5kA


General Information
Megawin make Cassette type Indoor Metal Clad vacuum circuit breaker is suitable for secondary distribution and infrastructure segment


Applicable standards 

Complies with IEC 62271-100 / 200 / 1.



  • Transformer switching 

  • Capacitor switching 

  • Motor switching 

  • Long feeder control


Product Features

  • Can be offered in conventional spring operated mechanism or magnetic actuator mechanism

  • Very compact. Thereby significantly reduces civil cost

  • It provides total safety to the operating personnel as all operations are facilitated in door-closed condition only

  • It has sufficient head room in the cable chamber i.e, more than 650mm which provides ease in bending & terminating power cable in cable box chamber

  • Compact yet modular

  • Fixed isolating contacts embedded in seal off bushing provides total segregation amongst high voltage compartments within the cubicle

  • It has 4 distinct high voltage compartments. Thereby offers the benefit of replacing PT primary fuse without switching off the incomer

  • Mechanical push to TRIP and CLOSE buttons can be provided for operation in closed door condition
