Products Description
Introduction
DKLINE ZW32-12KQ vacuum circuit breakers are engineered for power sampling, fault isolation, and seamless primary and secondary integration in smart distribution networks. Built with national technical patents, advanced circular ceramic capacitors for 12 power-taking channels (expandable to 15) and 6 current sampling channels, and a bistable double-coil repulsion magnetic drive mechanism, these breakers deliver fast, synchronous breaking to reduce pulling arcs and current impacts. Featuring an integrated waterproof and anti-EMI FTU, medium-voltage online carrier technology, an automated battery heating system below 0°C, and handheld APP control, the system achieves a controller fault detection response time of 2.64ms and a complete fault removal time of 11.68ms to prevent voltage dips and "fault crossing" across all regions and climates.

Products Overview
Characteristics
Integrating advanced power-sampling ceramic capacitors and a bistable magnetic-actuated drive, this outdoor column vacuum circuit breaker boasts a highly streamlined direct-acting mechanism compared to traditional spring breakers, reducing internal components from over 100 to under 40 and significantly lowering mechanical failure risks. Built with national technical patents and certified to IEC 62271-100 standards, the breaker features a rated voltage of 12kV, 630A rated current, and 12.5kA short-circuit breaking capacity, providing exceptional insulation performance and 10,000-cycle mechanical durability across extreme temperatures from -40°C to +70°C and altitudes up to 5,000 meters.
This product is engineered for smart 12kV distribution networks requiring high-precision telemetry, remote grid management, and severe weather resistance. Where rapid fault isolation and intelligent automation are required, its integrated FTU and medium-voltage online carrier technology provide a far superior solution than conventional switchgear-achieving fault detection within 2.64ms and total clearing in 11.68ms to instantly eliminate power dips and prevent "fault crossing" without site visits.
