Product Overview & Technical Architecture

What is Lighting Distribution Board (LDB)?

Panel Electro Lighting Distribution Boards (LDB) manage interior, street, and perimeter lighting circuits with astronomical digital timers, photocells, and contactors to optimize energy usage.

Capable of handling high continuous currents up to 6300A, a PCC panel houses heavy-duty Air Circuit Breakers (ACBs), Molded Case Circuit Breakers (MCCBs), high-capacity busbar chambers, numerical protection relays, and smart digital power quality meters.
