VEP circuit breaker originates from Germany, and is the third generation medium voltage enclosed type vacuum circuit breaker which is researched and developed by senior experts from China and Germany together.

VEP circuit breaker is the third generation medium voltage enclosed type vacuum circuit breaker with the most complete product specification series in the world.

VEP circuit breaker has passed product type test and national product identification with a whole set of GB and IEC standards.

The pole of VEP circuit breaker encloses lower resistance type vacuum arc-extinguishing chamber and primary loop dominant electric part inside the epoxy resin, so it applies to adverse working conditions.

The enclosed pole of VEP circuit breaker has an application of patented buffer layer, which guarantees a more reliable enclosed pole in all kinds of operation environments.

The application of lower resistance type vacuum arc-extinguishing chamber in VEP circuit breaker has fundamentally satisfied the requirement on temperature rise of strong current VEP and reduced electric energy loss.

The modularized elastic spring actuator of VEP circuit breaker has high reliability and easy maintenance.

VEP circuit breaker can fully satisfy GB, GL, IEC, DIN VDE and the standards of other advanced industrial countries.

VEP indoor medium voltage enclosed type vacuum circuit breaker is the updating product of the second generation sleeve type vacuum circuit breaker.
