Eaton Air Circuit Breakers equipped with Arcflash Reduction Maintenance System™ (ARMS)

An Eaton air circuit breaker equipped with ARMS can improve safety by providing a simple and reliable method to reduce fault clearing time. The ARMS is controlled by a lockable switch that can easily activate a separate analog circuit for faster tripping time at the work location and be incorporated into a Lock Out Tag Out (LOTO) procedure. Downstream of a circuit breaker equipped with an Arcflash Reduction Maintenance System can have a significantly

lower incident energy level, thus protecting operators or maintenance personnel who are working on a downstream energized piece of equipment.

Benefits of Arcflash Reduction Maintenance Systemare:

• Increased personnel safety by limiting the available arc flash energy.

• Simple to operate.

• Enabled with the circuit breaker door closed by a door mounted lockable switch or through communication to the breakers trip unit

• Enabled only for the time required to perform the work.

• Preserves over-current coordination under normal onditions.

Arc ignition protected zone & Arc tested zone\*

Eaton's philosophy is that the best way to mitigate the risks of internal arcingis to prevent the arc from happening in the first place.

Arc ignition protected zone - part of a circuit within the assembly where it is not possible to apply an ignition wire without destroying the insulation material on conductors

Arc tested zone - Part of a circuit where an ignition wire can be applied and fulfilling all relevant criteria for the assessment of the test
