Advanced COTS (commercial-off-the-shelf) TechnologyActron circuit breakers are based on leadingcommercial circuit breaker technologies.

Advanced FeaturesActron circuit breaker features allow increasedautomation and reduced manning throughlocal and remote state monitoring of circuitbreaker parameters.

Among the many new features are RMSSensing, Rating Plugs, Adjustable Short-TimeDelay Trip, Adjustable Instantaneous Settingsup to 50 times the frame rating, Ground FaultDetection, Real-Time State Monitoring,Bidirectional Communications and ControlFunctions and more.

Universal Circuit Breaker ApplicationEach Actron circuit breaker can be used forthe complete range of continuous currentsettings of that frame size.

Significantly Reduced Logistics CostsThe universal application of the Actroncircuit breakers reduces parts inventory andmaintenance, which lowers logistics costs.

Interchangeability withExisting Circuit BreakersActron circuit breakers meet the form, fitand function requirements of existing circuitbreakers in the Navy fleet.

Enhanced FeaturesThe electronic design of the Actron circuitbreakers allows for higher endurance ratingfor the shunt trip and undervoltage features,as much as four times to six times higher thanolder and competitive models.

Increased AdjustableInstantaneous SettingsActron circuit breakers have adjustableinstantaneous settings as high as 50 times theframe rating, providing increased selectivity,flexibility and reduced cost.

Significantly Increased CoordinationThe Actron series represents a whole newgeneration of “smart,” tough, reliable circuitbreakers that have won the United StatesNavy’s QPL approval rating. In fact, the Navy’sown analysis conducted on surface combatantsshows that electronic circuit breakers achievea 70% increase in electrical coordination overolder and competitive models.

More Automation, Reduced ManningActron circuit breakers have microprocessorsthat automatically and continuously monitora host of current parameters. This providesthe capability for on-board automation andreduces manpower requirements and costs.

Less Hardware, Lower CostsIn the past, Navy circuit breakers used eitherthermal magnetic or electromechanical tripunits for overcurrent protection. By integratingelectronic overcurrent protection in the Actroncircuit breakers, L-3/SPD Electrical Systemseliminates the need for costly trip units. Everyframe size has all-continuous current settingsincluded and requires only a change in theswitch settings or rating plug. This providessimplified ordering, application versatility,reduced parts inventory and reducedmaintenance resulting in manpower savings.

State Monitoring provides monitoring of the following functions:■ Ground Fault ■ Type & Phase of Last Trip ■ Phase Current■ Current Data Logging ■ Bidirectional Communication■ Remote Opening & Closing of Circuit Breaker

Advanced COTS (commercial-off-the-shelf) TechnologyActron circuit breakers are based on GroupeSchneider’s Masterpact circuit breaker, theleading air circuit breaker in the world.

Advanced FeaturesActron circuit breaker features allow increasedautomation and reduced manning throughlocal and remote state monitoring of circuitbreaker parameters.Among the many new standard features areRMS Sensing, Ground Fault Detection, Real-TimeState Monitoring, Bidirectional Communications,Control Functions, Undervoltage Dropout,Undervoltage Lockout, Power-Up Trip, ChargingMotor Protection and more.

Universal Circuit Breaker ApplicationEach Actron circuit breaker has continuouscurrent settings and standard features included,and requires only a change in switch settingsto reconfigure the circuit breaker.

Significantly Reduced Logistics CostsThe universal application of the Actroncircuit breakers reduces parts inventory andmaintenance, which lowers logistics costs.

Smaller and Lighter Air Circuit BreakersActron circuit breakers are as much as one-halfof the size and weight of existing air circuitbreakers. That means reduced size and weightfor switchgear as well!

Interchangeability withExisting Circuit BreakersActron circuit breakers can meet the form, fitand function requirements of existing circuitbreakers in the Navy fleet through the useof the Actron retrofit kit.

Significantly Increased CoordinationThe Actron series represents a whole newgeneration of “smart,” tough, reliable circuitbreakers that have won the United StatesNavy’s QPL approval rating. In fact, the Navy’sown analysis conducted on surface combatantsshows that electronic circuit breakers achievea 70% increase in electrical coordination overolder and competitive models.

More Automation, Reduced ManningActron circuit breakers have microprocessorsthat automatically and continuously monitora host of current parameters. This providesthe capability for on-board automation andreduces manpower requirements and costs.

Less Hardware, Lower CostsIn the past, Navy circuit breakers used electro-mechanical trip units for overcurrent protection.By integrating electronic overcurrent protectionin the Actron circuit breakers, L-3/SPD ElectricalSystems eliminates the need for costly overcurrentassemblies. With the flexibility provided by theActron circuit breaker, this provides simplifiedordering, application versatility, reduced partsinventory, and reduced maintenance resultingin manpower savings.
