Superior protection performance
With a global installed base of over 2 million units and superior performance than the market norm, ABB’s flagship product family of VD4 circuit breakers for primary and secondary protection can help you increase productivity while reducing downtime. Protect your assets with the industry’s most comprehensive array of circuit breakers, covering global standards and ratings to meet your specific requirements.
The scope of the product
Mechanical actuator (spring mechanism) medium voltage circuit breakers for primary distribution up to 46 kV, 4000 A, 63 kA.
Key Advantages
Among medium voltage vacuum circuit breakers, this is the most adaptable and powerful option.
Suitable for any purpose (eg, capacitor bank switching, marine, GOST)
Over 2 million VD4 medium voltage vacuum circuit breakers have been placed around the world.
OEMs and panel builders can construct their own solutions using cassettes and module systems.
ABB VD4 medium voltage gas circuit breaker is fully interchangeable — both in terms of overall dimensions and electrical diagram.
Only one common plug-and-play actuator (EL type) from 12 kV to 36 kV, with a large choice of accessories, safety locks and interlocks, and with the same family feel as ABB’s low voltage series EMAX.
Key Features
For protection against humidity, shocks, and dust, vacuum interrupters are placed in poles.
The spring-operated mechanical actuator is modular, allowing for easy functioning even when there is no power supply.
On most ratings, 30,000 mechanical operations are required.
Rated up to 46 kV, 4000 A, and 63 kA.
