Product Description

HVD11-1.14 Permanent magnet mechanism INDOOR HIGH VOLTAGE VACUUM CIRCUIT BREAKER

General：

HVD11-1.14 Permanent magnet mechanism Vacuum Circuit Breaker is mainly used in 1140v or 660v three phases electrical distribution system. Permanent magnet low-voltage vacuum circuit breakers can be operated under the rated current range frequently breaking the short-circuit current, more suitable for use in coal mine feed systems, composed of mining and high voltage flameproof distribution. ALso could use for Large-capacity motors for start infrequently.

This product uses bistable permanent magnet mechanism + short-circuit magnetic manual opening, simple structure, stable and reliable. Because there is no axle, hook and other mechanical parts, greatly reduced the mechanical parts failure caused by wear and tear, Longer service life.
