About Vacuum Circuit Breaker
It is a highly sophisticated electrical safety measure device applied to break and isolate faults in medium-voltage power systems. Vacuum Circuit Breaker is a type of Circuit Breaker that uses vacuum as an arc-quenching medium and is fast, safe and maintenance free. It is also very common in the industry and utility sector where it has a high level of reliability and service life. ABB Vacuum Circuit Breaker in Pune is one of the widely trusted brands we supply. Retrofit Vacuum Circuit Breaker solutions are available to upgrade existing installations proficiently.
Types of Vacuum Circuit Breaker
As Vacuum Circuit Breaker Suppliers in Pune, we provide customized VCB solutions for industrial and utility applications.
- Pole-Mounted Type (Insulation Cylinder): This type Vacuum interrupter is enclosed within an insulation cylinder. It is superb electrically insulated, easy to maintain and install flexibly. Pole-mounted vacuum circuit breakers are very common in medium-voltage distribution systems where reliability and maintainability are essential parameters.
- Pole-Enclosed Type (Epoxy Resin Casting): The type has a vacuum interrupter that is entirely covered by epoxy resin casting giving it a great deal of mechanical strength and shielding against dust, moisture, and environment stress. Vacuum circuit breakers with poles are unique in compact switchgear and in the severe operating conditions to maintain the stability and safety during the long-term.
- Low Voltage Vacuum Circuit Breaker: They are designed to work at lower voltages, have quick fault interruption and are more operationally safe. Low voltage vacuum breakers like Motor Protection Circuit Breaker are those utilized in commercial properties, small industries and auxiliary power systems.
- Medium Voltage Vacuum Circuit Breaker: It is the most common type, which is applicable to a voltage span of about 3.3 kV to 36 kV. They offer quick breaking capacity, low maintenance and dependable arc quenching to the industrial plants, substations and utility networks. Crompton Greaves Vacuum Circuit Breaker is a popular choice in this category.
- High Voltage Vacuum Circuit Breaker: They are designed in high-capacity power transmission and distribution networks. They also provide effective fault isolation, system reliability and extended service life in essential infrastructure like power grids, and substantial substations. 33KV Outdoor Vacuum Circuit Breaker and Lucy Vacuum Circuit Breaker are examples of high-performance options.

Benefits of Vacuum Circuit Breaker
As Vacuum Circuit Breaker Traders in Pune, our systems are corrosion-resistant and suitable for harsh environmental conditions.
- Superior Arc Quenching: Vacuum technology also eliminates electrical arcs quickly, at high currents, contact wear, and guarantees a reliable operation.
- Low Maintenance and Long Service Life: There is minimal contact erosion that enables tens of thousands of operation cycles with minimal maintenance.
- Environmentally Friendly: The harmful SF6 gas and oil are not used in VCBs, and hence VCBs are a cleaner and safe alternative to power systems.
- Compact & Lightweight Design: Arc interruption can be efficiently interrupted to permit smaller, self-contained units, which can be installed in limited space.
- High Safety and Reliable Performance: Safe, reliable power distribution is provided by no threat of fire or explosion, silent operation, and high fault current interrupting capability.
Applications of Vacuum Circuit Breaker
As Vacuum Circuit Breaker Suppliers in Pune, our VCBs are widely used in substations and industrial power networks.
- Medium Voltage Distribution Systems: VCBs are used in medium voltage networks with a current of 11 kV to 33 kV and they are used to ensure a safe and efficient switching of the network as they protect the network against overloaded and short circuiting.
- Motor Control Centres (MCCs): They ensure safety and good security to massive motors in the industries to avoid damage caused by electrical faults, and they also smooth run of machines.
- Industrial Infrastructure: VCBs are placed in power distribution panels of factories and plants, which provide reliable fault clearance, reduce downtimes, and ensure operations are continuous in a factory setting.
- Renewable Energy Integration: Vacuum Circuit Breakers have been used in solar and wind power systems to effectively switch and protect their equipment to guarantee a steady flow of energy.
- Substations & Railway Traction: They are applied in electrical substations, railway traction systems to offer both primary and secondary protection, to allow safe and reliable operation of high-power transmission and train electrification networks. Lucy VCE is commonly used here.
