Instructions Manual

 

DIVAC® is a three pole circuit breaker that uses vacuum interrupting technology.

 

 

GENERAL CHARACTERISTICS

  • Safe and reliable

  • Compact design

  • Suitable for every field of application in Medium Voltage

  • Excellent dielectric and arc quenching properties

  • Complete arc self-extinguishing properties

  • Easy installation

  • User-friendly operation

  • Extended electrical and mechanical life

  • Maintenance free

  • Several optional equipments are available

 

CONSTRUCTION PHILOSOPHY

  • Sheet baseframe that supports both the poles and houses the operating mechanism.

  • Circuit breaker made up of three column shaped poles.

  • All circuit-breaker live parts are housed inside an epoxy resin envelope, which eliminates the possibility of arcing faults earth.

  • The Divac range uses a stored energy spring operating mechanism. the basic version is fitted with a manual charging device and, optionally, with a charging motor. When the mechanism is fitted with a charging motor, it is suitable for autoreclosing and also for multi-shot autoreclosing fast cycles.

 

THE DIVAC CIRCUIT BREAKERS RANGE CAN BE USED FOR:

 

  • Open space substations

  • Assembly in compartment cubicles

  • Assembly in Metalclad cubicles

  • Retrofitting breakers
