A VCB in One Minute

A vacuum circuit breaker (VCB) switches load and interrupts fault current. When a fault occurs, the contacts inside a sealed vacuum interrupter separate and the arc is extinguished in the vacuum. Because there is no oil to handle, routine maintenance stays low. An indoor VCB is built to sit inside a building, in a switchgear panel, protected from rain, dust and sun.

Indoor or Outdoor: Which VCB Do You Need?

• Choose an indoor VCB if you have a switch room or a building for your switchgear. This is the usual choice for factories, commercial complexes and substations with a dedicated room.
• Choose an outdoor breaker if your equipment will stand in an open yard. See our outdoor vacuum circuit breakers.
• For lighter pole-top duty, see our polymer clad vacuum circuit breaker.

Where an Indoor VCB Is Used

• Incomer and outgoing feeders in industrial plants.
• Transformer protection in commercial buildings and campuses.
• Distribution substations and switch rooms.
• Renewable energy plants with an indoor switchgear room.
• Motor and capacitor feeders in factories.

Fixed or Withdrawable: A Quick Guide

A fixed breaker is mounted permanently in the panel and suits simple installations. A withdrawable breaker can be moved out of the panel for inspection or replacement, which helps when you cannot afford long shutdowns. Tell us which arrangement you prefer, and we will confirm the options for your project.

Indoor VCB Supplier in India: Frequently Asked Questions

What voltage range do your indoor VCBs cover?
Our indoor vacuum circuit breakers cover 11 kV up to 36 kV class. Share your system voltage and we will confirm the right unit.

What is the difference between a fixed and a withdrawable VCB?
A fixed breaker stays in the panel. A withdrawable breaker can be taken out for inspection or replacement without removing the whole panel.

Does a VCB need a protection relay?
Yes. The breaker acts on a trip signal from a protection relay, which reads current through current transformers.

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

Can an indoor VCB be installed outdoors?
No. An indoor unit is not built for rain, dust and sun. For an open yard, use an outdoor breaker.

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