JC-V/12-630A-25 Circuit Breaker + Isolator Switch Mechanism (Pushbutton Type)

The JC‑V series circuit breaker mechanism is a complementary device designed for the closing and opening operations of circuit breakers installed in gas‑insulated high‑voltage ring main units. This series employs a tension spring that passes through the neutral point to control the closing action, while the opening operation is driven by a compressed spring‑energy storage system. The product features a reclosing function and, when used in conjunction with an isolating mechanism, provides interlocking functionality. It offers high reliability, with a mechanical life exceeding 10,000 operations. All units in this series undergo full inspection prior to shipment and comply with the common technical requirements specified in GB 1984‑2014, the standard for high‑voltage switchgear and control equipment.
