OUTDOOR VCB
The EOFVp-36 is the result of consistent further development for application in modern current interruption technology for medium voltage switchgear. It is characterized by compact dimensions. Good operator guidance and a modern functional industrial design. The EOFVp-36 is a porcelain-clad outdoor vacuum circuit breaker supported on steel frames and designed for plinth mounting and is for use on earthed systems. It requires minimum maintenance compared to other circuit breaker technologies and can perform well in harsh conditions. The mechanism of this breaker is designed for the operation of very a short stroke required in vacuum interrupter.
- Three pole operation system
- Robust vacuum interrupters
- Operating mechanism motor driven
- Fully spring-operated mechanism for all range
- Tested to IEC standard
- Simple to install and operate
- Long service life that other types of breaker
- Maintenance reduced at the mInImum
- Operates in all kinds of extreme climate conditions
- Increased safety High mechanical endurance
- Environment friendly in comparison to other types of circuit breaker
