Over the last five decades, L&T Electrical & Automation (E&A) has earned a place among the leading manufacturers of Low Voltage Switchgear with scale, sophistication and range to meet global benchmarks.

Electrical power is the lifeline of the industry but it is unpredictable. Just like an ocean, it can be calm one moment and turbulent the next. You cannot predict the next course of electrical turbulence. That is where our highly sophisticated OMEGA Air Circuit Breakers (ACBs) can make a world of difference.

OMEGA ACBs are the next-generation air circuit breakers with advanced protection features designed to protect an electrical system from damage caused by excess current from an overload or short circuit and equipment ground faults. 

Designed for Indian conditions, OMEGA  Low Voltage (LV) circuit breakers are available in the current range from 400A to 6300A and meet the most demanding protection and system coordination requirements.

Omega ACB is designed for high current, high power application in LV distribution network systems and cater to the needs of various segments like Industry, Infra, OEMs, Utilities etc.

The compact and space-saving design offers flexibility, easy assembly, and supports communication interfaces to integrate with SCADA or energy management systems.

This product was awarded the 'Best Product' at ELECRAMA.
