Vacuum Circuit Breakers Manufacturer for Reliable Power Distribution

Dongfa Intelligent provides project sourcing and technical selection of the 12kV Indoor Embedded Pole Vacuum Circuit Breaker, designed for compact and reliable indoor medium-voltage power distribution systems. The ZN63(VS1)-12 integrates the vacuum interrupter into an embedded pole structure to provide stable insulation and a more compact switching assembly. With rated current options from 630A to 4000A, short-circuit breaking capacity up to 40kA, and flexible switchgear integration, it is suitable for utilities, power plants, mining and industrial applications. Model: ZN63(VS1)-12 Parameters: 12kV |630A–4000A |20/25/31.5/40kA

Dongfa Intelligent supports sourcing and technical selection of the 12kV Indoor Permanent Magnet Vacuum Circuit Breaker for indoor medium-voltage power distribution systems. The ZN63A(VS1)-12 uses a bistable permanent magnet operating mechanism that reduces mechanical components and shortens the transmission chain compared with conventional spring mechanisms. With up to 20,000 mechanical operations, short-circuit breaking capacity up to 40kA, and multiple rated-current configurations, it is designed for utilities, power plants, mining and industrial applications.
