L&T’s Air Circuit Breakers (ACBs) are specially designed for extreme tropical conditions and have a proven track record of more than 5 decades. Presently more than 5,00,000 ACBs supplied by L&T are being used for diverse applications. C-Power provides technologically driven solutions to meet customer needs.

Over the years, this breaker has proved its credentials as a “rugged breaker”.  Its  level of performance has now become a benchmark worthy of emulation in the market.

C-Power rating ranges from 400A to 6300A with breaking capacities from 50kA to 100kA.

C-Power has been inherently designed to perform in extreme tropical climates. Typical site conditions like high ambient temperatures, humidity and dusty environments are best handled by C-Power ACBs without compromising on performance and safety.
