Air Circuit Breakers: C-Power

To protect your electrical assets, L&T Electrical & Automation (E&A) offers a complete range of Air Circuit Breakers (ACBs) up to 6300A. The C-Power range of ACBs is designed and manufactured to protect electrical systems and machines from overcurrent and short-circuit.

The C-Power ACBs address every single need of a power distribution system to keep your operation running safely and efficiently

The modular design and standardized range of ACBs are suitable for a wide range of electrical applications in Buildings, Infrastructure, and Industries.

Combining scalability, durability, and connectivity, the C-Power ACBs incorporate the latest digital technologies to provide improved power uptime and energy efficiency.

Designed for extreme tropical conditions, the ACBs are being used for diverse applications and have, over the years, proved their credentials as a “rugged breaker”. Typical site conditions like high ambient temperatures, humidity, and dusty environments are best handled by C-Power ACBs without compromising on performance and safety. Their level of performance has become a benchmark in the market.
