Circuit Protection Review 
Diversified industrial manufacturer Eaton has launched a new series of versatile circuit-breakers. The new NRX series, which includes the smallest air circuit-breaker in the world, offers different rated currents for a wide range of applications from 630 A to 4000 A and breaking capacities from 42 kA to 105 kA.
EntelliGuard™G Power Circuit Breakers line of Air Circuit Breakers that have evolved from the previous M-PACT & ME07 types to offer a truly global product platform meeting IEC, ANSI and UL standards available from 400 to 6400A in three basic envelopes with fault interruption ratings of up to 150kA. The design offers a unique combination of High Fault current withstand ratings, fast fault interruption times and selectivity.
ABB has launched Emax 2, the first low-voltage circuit breaker with integrated energy management functions. Replacing existing traditional breakers with the Emax 2 breaker has the potential to achieve annual savings of 5.8 million megawatt-hours (MWh).
Meeting the challenge Magnum breakers are engineered specifically for use in low voltage assemblies applied at nominal voltages of 380, 415, 440, 500 and 690 Vac.
Air Circuit Breakers (ACBs) are used as circuit protection for a wide range of low voltage (up to 600V AC) applications, typically generators, MCCB distribution boards, UPS, small power stations, etc with sizes ranging from 400A to 6300A or larger.
As part of the Sentron product portfolio, the 3WL11 can be flexibly used as an incoming feeder circuit breaker, distribution circuit breaker, tie circuit breaker and outgoing feeder circuit breaker in practically all applications.
EntelliGuard™G is a new line of Air Circuit Breakers evolved from the existing M-Pact & ME07 series to offer a truly global product platform meeting IEC, ANSI and UL standards.
