Breaker + disconnector module for gas-insulated cabinets: 20 kA/4 s · 25 kA/3 s withstand, 10,000-operation breaker life, ≤ 60 μΩ loop resistance and ≤ 2 ms phase asynchronism.
The VD□-12/24 vacuum breaker with disconnector is easy to install, low-maintenance, long-lived, compact, economical, safe and reliable. It complies with GB 1984-2014 (HV AC circuit-breakers) and GB/T 1985-2023 (HV AC disconnectors and earthing switches). Main-circuit withstand reaches 20 kA/4 s and 25 kA/3 s; mechanical life is 10,000 operations for the breaker and 3,000 for the disconnector; the earthing switch withstands 20 kA/4 s with 3,000-operation life.
