11KV Outdoor VCB Supplier in India

The 11KV Outdoor VCB from Arpan Power Projects is an outdoor vacuum circuit breaker for 11 kV networks. It switches load, interrupts fault current and protects the lines and transformers connected to it, and it is designed to stand in the open without a building around it. As an 11KV Outdoor VCB Supplier in India, we help you choose the right unit and support you from enquiry to commissioning.

The 11KV Outdoor VCB in Four Lines

• What it is: a three-pole outdoor circuit breaker that uses a vacuum interrupter.
• What it does: switches load and clears faults on an 11 kV line or feeder.
• Where it stands: outdoors, in a substation yard or on a support structure.
• What it works with: current transformers, a protection relay and a control box.

How an 11KV Outdoor VCB Protects Your Line

When a fault occurs, the protection relay senses it through the current transformers and sends a trip signal to the breaker. The contacts inside the vacuum interrupter then separate and the arc is extinguished in the vacuum, so the faulty section is cut off quickly and the rest of the network stays healthy. Because the interruption happens in a sealed vacuum interrupter, the 11KV Outdoor VCB needs less routine maintenance than breakers that depend on oil. 11 kV systems are typically served by 12 kV class equipment, so check the datasheet of the unit you choose.

Where an 11KV Outdoor VCB Is Installed

• Incoming and outgoing feeders in an outdoor 11 kV substation.
• Protection of distribution transformers on an 11 kV line.
• Industrial plants that take supply at 11 kV and have an open switchyard.
• Renewable energy plants that connect to an 11 kV network.
• Sectionalising points on long overhead lines.

11KV Outdoor VCB Supplier in India: Frequently Asked Questions

What is an 11KV Outdoor VCB?
It is a vacuum circuit breaker built for outdoor use on 11 kV networks. It interrupts fault current inside a sealed vacuum interrupter.

Why choose vacuum technology for an 11 kV breaker?
The arc is extinguished inside a sealed vacuum interrupter, so there is no oil to handle and routine maintenance is lower.

Does the breaker need a relay?
Yes. The breaker acts on a trip signal from a protection relay, which reads current through current transformers. We can supply the control and relay panel along with it.

Can an indoor breaker be used outdoors?
No. An outdoor unit is built for rain, dust and sun, so an indoor breaker should not be left in an open yard.

What details do I need to share for a quotation?
Share your voltage, rated current, fault level, number of feeders, mounting arrangement and site location.

Do you supply across India?
Yes. Arpan Power Projects supplies across India. Send your requirement through our contact page.
