Omega Air Circuit Breaker

Omega Air Circuit Breaker

Over the last five decades, Larsen & Toubro has earned a place among the leading manufacturers of Low Voltage Switchgear in the world, with the scale, sophistication and range to meet global benchmarks.

Electrical power is the lifeline of 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’s where our highly sophisticated OMEGA ACBs can make a world of difference.

OMEGA ACBs are the next generation breaker with advanced protection features. This product was Awarded as the 'Best Product' at Elecrama.
