The VCB�s and the panels have been optimally designed for Indian local electric supply conditions and ambient. All critical parts are manufactured on CNC machines and finished products are subjected to stringent quality tests in accordance with documented procedures, which are in line with international standards. The Vacuum Circuit Breakers are rated upto 12kV, 1250A, 3Ph. 50Hz. with a short-circuit breaking current upto 25kA. The construction is compact in design, fully fabricated.

Designed for use with air insulated
metal enclosed switchgear and
controlgear and indoor applications. EVK CB’s are suitable to rapid
auto-reclosing.
The switching tests of breaker were
carried out inside MME* type
cubicle.

According to Paschen Curves, high values of dielectric strength of medium can be obtained at very low or very high pressure levels. The characteristics of insulation at very low pressure values provide very low distance between contacts. This distance varies from 10 mm to 20 mm considering the voltage level.

Vacuum circuit-breakers does not require an interrupting or insulation medium. In fact, the interrupters do not contain ionizable material.

Advantages of Vacuum Circuit Breakers:
� Very long lifetime of the contacts (This provides longer breaker life.)
� Less maintenance required
� Less moving parts in mechanism
� Less force needed to separate the contacts (since the distance between them is shorter.)
� Environment friendly. Since interruption takes place in vacuum medium, VCBs do not require
gas or liquid addition. This reduces the possibility of leakage of gas (or any material) that can
be harmful for environment.

Reliable VCB (Vacuum Circuit Breakers) for Efficient Power Protection

Vacuum Circuit Breakers (VCBs) are one of the most advanced and efficient solutions for high-voltage power protection. Designed for enhanced safety, durability, and low maintenance, VCBs use a vacuum as an arc-extinguishing medium, ensuring quick fault clearance and reliable operation. These circuit breakers are widely used in power plants, industrial facilities, substations, and commercial buildings where dependable power distribution is essential.

Why Choose VCBs for Your Power Systems?

Superior Arc Quenching – The vacuum technology ensures fast and effective arc extinguishing, reducing electrical hazards.
Low Maintenance & Long Life – With minimal moving parts and no need for regular refilling, VCBs have an extended lifespan.
High Efficiency & Performance – Designed for high-voltage applications, these breakers offer quick switching and minimal energy losses.
Environmentally Friendly – Unlike oil or gas circuit breakers, VCBs do not use harmful insulating materials, making them a greener alternative.
Compact & Space-Saving – Their compact size allows for easy installation in various applications.
Cost-Effective Solution – VCBs provide long-term savings by reducing maintenance costs and ensuring efficient power management.

Applications of Vacuum Circuit Breakers (VCBs)

Power Plants & Substations – Ensuring uninterrupted power supply with fast fault clearance.
Industrial Units – Providing reliable protection for heavy machinery and electrical systems.
Commercial & Residential Buildings – Safeguarding electrical networks from overloads and short circuits.
Railways & Metro Systems – Used for power transmission and distribution in transportation networks.
Renewable Energy Projects – Essential for wind and solar power systems, ensuring stable operation.
