L3 SPD Electrical Systems' air circuit breakers allow for increased automation and reduced manning through local and remote-state monitoring of circuit breaker parameters. Our air circuit breakers are based on Eaton's Magnum Double Narrow circuit breaker, the leading circuit breaker in the world.

Many new standard features include RMS sensing, ground-fault detection, real-time state monitoring, bidirectional communications, control functions, undervoltage dropout, undervoltage lockout, power-up trip, charging motor protection and more.

By integrating electronic overcurrent protection in the air circuit breakers, L3 SPD Electrical Systems eliminates the need for costly overcurrent assemblies. This flexibility provides simplified ordering, application versatility, reduced parts inventory and reduced maintenance, resulting in manpower savings.
