Frequently Asked Questions (FAQs)

Q1. What is a Crompton Greaves VCB used for?
CG VCBs are used to protect electrical equipment by interrupting short circuits and overload currents in medium-voltage applications.

Q2. How does a CG VCB work?
The breaker interrupts current by separating contacts in a vacuum, which quickly extinguishes the arc with minimal contact erosion.

Q3. What makes CG VCBs a preferred choice?
Crompton Greaves offers reliable performance, locally available spares, strong service support, and compliance with international standards.

Q4. What are the available types of CG VCBs?
CG offers indoor panels, outdoor breakers, fixed and draw-out types, with or without control and protection panels.

Q5. Is AMC (Annual Maintenance Contract) available for CG VCBs?
Yes, we provide AMC, on-site testing, relay calibration, contact resistance testing, and complete refurbishment for CG VCBs.

Q6. Can you retrofit old breakers with new CG VCBs?
Absolutely. We offer panel upgradation and retrofitting solutions for replacing outdated OCBs or faulty VCBs with new CG units.
