An indoor vacuum circuit breaker is an electrical device used for protection and safe operation of electrical circuits in indoor environments. It is designed to interrupt fault currents and provide overload protection in various electrical systems such as power distribution networks, industrial plants, and commercial buildings.
High reliability and safety: The vacuum interrupter technology ensures effective arc interruption and reliable operation, minimizing the risk of electrical faults and malfunctions.
Fast and accurate fault detection: The breaker is equipped with advanced protection and sensing mechanisms that quickly detect and respond to abnormal electrical conditions, protecting the connected equipment and preventing further damage.
Compact and space-saving design
The compact size of the indoor vacuum circuit breaker allows for efficient utilization of available space in indoor installations, making it an ideal choice for applications with limited space.
Minimal maintenance
The vacuum interrupter technology eliminates the need for regular maintenance tasks such as oil refilling or gas monitoring, resulting in cost savings and reduced downtime.
Environmental friendliness
Unlike circuit breakers that use oil or other gases, the indoor vacuum circuit breaker does not release any harmful substances or pollutants into the environment, making it an eco-friendly choice.

Application of Indoor Vacuum Circuit Breaker
Power Generation and Distribution: IVCB are widely used in power plants, substations, and utility networks to manage and protect distribution systems. They ensure that, in case of overloads or short circuits, the flow of electricity is quickly interrupted, preventing damage to other equipment and minimizing the risk of widespread outages.
Industrial Manufacturing: Manufacturing facilities rely heavily on uninterrupted power for machinery and production lines. Industries like automotive, steel, cement, and chemical manufacturing use IVCBs to protect their equipment from electrical faults. IVCBs are favored due to their durability and low maintenance needs, which reduce downtime and maintain high operational efficiency.
Renewable Energy: In wind and solar power systems, IVCBs protect the equipment from electrical fluctuations and faults. Renewable energy systems are often located in remote or harsh environments, and IVCBs offer high reliability, durability, and resilience to frequent switching operations necessary for renewable sources.
Commercial and Residential Buildings: In urban infrastructure, IVCB are used in high-rise buildings, shopping centers, hospitals, and data centers, where stable and safe electricity is essential. Indoor IVCB protect against potential faults that could otherwise lead to electrical fires or equipment damage, ensuring the safety of occupants and critical equipment.
Transportation and Railways: IVCB are essential in the rail sector to protect and control power systems used in electric trains and metro lines. They safeguard power networks in railways and metro systems from electrical surges, providing a dependable solution that ensures safe and reliable transit services.
The vacuum circuit breaker consists of fixed contact, moving contact and an arc shield mounted in a vacuum interrupter. The outer insulating body is made with glass and has a high vacuum capacity. The movable member is connected to the bellows.
The arc shield prevents the deterioration of the internal dielectric strength by preventing metallic vapors from falling on the inside surface of the outer insulating body. This allows reducing the chopping current up to 3.5 amperes. To reduce the leakage permanently, the tight sealing of the chamber is done.
The contacts use a large stem with disc shape faces. To dissipate heat for large overload current during arcing, contact materials like copper alloy is used.
Altitude: Up to 1000m;
Operating ambient air temperature range: -40°C (with heating option) to 40°C;
Industrial environment (type II as per GOST 15150)
Non-explosive environment that does not contain conductive dust, corrosive gases and vapors in concentrations that are destructive to materials and insulation;
Relative humidity up to 80% at the temperature 25°C;
Ambient air temperature during storage of packed and preserved products: -50°C to 40°C;
