NEC compliant arc energy reduction products

Magnum circuit breakers

Magnum DS power circuit breakers have the highest ANSI interrupting and withstand ratings in the industry in the smallest physical size and are the most easily maintained ANSI circuit breakers on the market.

Magnum SB insulated-case power circuit breakers are designed for the performance and economic requirements of UL 891. Both are ideal for switchgear and switchboards, providing excellent safety, flexibility and a high level of performance. 

All Digitrip trip units available in Magnum circuit breakers come standard with zone selective interlocking (ZSI) available. If purchasing new power distribution equipment, be sure to specify that the ZSI protection is wired between the trip units.

Power Defense molded-case and insulated case circuit breakers

Eaton's globally rated circuit breakers help reduce arc energy through our Arc Flash Reduction Maintenance System (ARMs), and visual zone selective interlocking (ZSI).   

ARMs helps to protect workers by reducing dangerous and potential arc flash incident energy levels, and enabling workers to activate this system from a safe distance without altering critical protection settings of the breaker.   

ZSI technology protects equipment by intelligently selecting faster trip times in coordinated systems, an advantage which can keep operators safe and productive. Power Defense MCCBs advance this proven technology by providing the ability to test the ZSI system functionality while visually indicating its operational status.

EBR-3000 Bus differential relay

Eaton's Bus Differential Relay is a digital protection relay designed for high impedance differential protection schemes. The intuitive operating system with validation checks and extensive commissioning functions such as, the built-in fault simulator, allow safe and time-optimized maintenance and commissioning.

Our Bus Differential Relay is also equipped with the  zone selective interlocking feature (ZSI), to help reduce arc energy.

• Arcflash Reduction Maintenance System available on Magnum breakers, Power Defense breakers, EMR, EDR and ETR protective relays
• Integrated Arcflash Reduction Maintenance System feature available in low voltage replacement circuit breakers for multiple generations of Westinghouse, Allis-Chalmers, Federal Pacific, General Electric and ITE

Eaton arc flash relay (EAFR)

Eaton’s Arc Flash Relay system helps improve worker safety and maximize electrical assembly uptime by quickly clearing arc flash events. Featuring factory-installed Arc Flash Relay modules and sensors, the system is designed to rapidly detect and clear even the most difficult forms of arc flash events in low-voltage (LV) and medium-voltage (MV) electrical assemblies. 

Eaton’s Arc Flash Relay system reduces the arc energy by clearing the current feeding the arc. 

Arc Quenching Magnum PXR low-voltage switchgear

• Reduces incident energy to below 1.2 calories per centimeter squared
• Provides arc-resistant protection without the need for ducts, plenums or special enclosure construction
  
• Exceeds arc-resistant test guide by providing arc-resistant protection even with doors open
• Protects switchgear from arc flash damage
• Reduces downtime from weeks to hours in the event of an arc flash
