FUNCTIONALITY
Our LT Panels function as the central nervous system of your electrical distribution network. Designed to receive power from the transformer or generator, these panels distribute electricity to various sub-circuits and loads while providing essential protection against overloads, short circuits, and earth faults. The panels house critical components like Air Circuit Breakers (ACBs), Molded Case Circuit Breakers (MCCBs), and switch disconnectors, all orchestrated by advanced protection relays. This centralized control allows for seamless power management, real-time monitoring, and safe isolation of circuits during maintenance.

Frequently Asked Questions
PCC (Power Control Center) panels are used for main power distribution, typically housing high-capacity incomers and feeders. MCC (Motor Control Center) panels are specifically designed to control and protect electric motors, featuring contactors, VFDs, and overload relays for motor operations.
Our LT Panels are strictly designed and type-tested in accordance with IEC 61439-1 and IEC 61439-2 standards. We also adhere to Indian Standards IS 8623 for construction and safety requirements.
Yes, absolutely. We offer fully customized solutions. Our design team works with your electrical layout to optimize the panel dimensions (width, height, depth) to fit within your available electrical room space.
