33kV VCB Panel/Switchboard
Our Medium voltage panel or switchboard (MV panel or switchboard) is primarily designed for 33kV applications, ensuring reliable power distribution and protection. The 33kV VCB panel or switchboard integrate Vacuum Circuit Breakers (VCB), Current Transformers (CT), Potential Transformers (PT), Relays, and Meters to safeguard feeders and transformers efficiently. Available in 800A – 20/18.4kA, 1250A – 26.3kA, and ≥1600A – 40kA, this panel or switchboard provides customizable breaker configurations to meet diverse site requirements. While predominantly designed as indoor units, it can be tailored for outdoor installations based on specific environmental needs.
