VZF-12R Indoor High Voltage VCB Solid Vacuum Circuit Breakers

Indoor high-voltage VCB (Vacuum Circuit Breaker) solid-state vacuum circuit breakers are advanced devices designed for indoor electrical distribution systems. Utilizing solid-state technology and vacuum interrupters, these circuit breakers offer outstanding current interruption capabilities, efficiently protecting electrical systems from overloads and short circuits. Their compact design makes them suitable for installation in substations, electrical rooms, and other indoor environments.
These VCBs are characterized by their quick operation, ensuring rapid disconnection of faulty circuits to maintain the safety and stability of the power grid. With low maintenance requirements and a long lifespan, they reduce downtime and maintenance frequency, contributing to high reliability. Additionally, these solid-state VCBs can be integrated with smart control systems for remote monitoring and operation, enhancing the automation and intelligence of the electrical system.

  • Overview

    VCF series AC high voltage vacuum contactor-fuse combination electrical appliance (F-C) is suitable for AC 50-60Hz, main circuit rated working voltage is 7.2kV, 12kV. It has a flexible function combination, compact and reliable structure, multiple protection features, long service life and frequent operation. It can be widely used to break and close load circuits such as AC motors and transformers, and can also be used for capacitor reactive power compensation.

    VCF series combination electrical appliances adopt modular combination structure, can be used with single contactor or combined into F-C use, optional fixed or handcart mobile type, handcart type can be used with 650mm or 800mm wide KYN28A (GZS1) type central cabinet, can be used to replace VSC/P vacuum contactor.

    VCF Series AC high voltage vacuum contacts for fuse combination appliances are compliant with national standards GB/T 14808 and GB/T 11022.

    Normal conditions of use

    ◆For indoor use, the ambient air temperature is not higher than +40 °C and not lower than -25°C .

    ◆The altitude of the installation site does not exceed 1000 meters.
