Comparing Zenergy Power Fault Current Limiter to Conventional I s -Limiter Zenergy Power FCL Conventional I s -Limiter Fault Current Reduction Instantly inserts impedance to reduce current.Instantly recovers when fault is cleared.Fault Current Interruption Instantly interrupts current.Requires manual reset.Automatic recovery Able to recover under load and provide protection during multiple reclosure sequences.Single use devise Requires operator intervention to reset.Completely passive No fault current detection required.Limitation is due to a materials property.Requires detection of fault current Electronic triggering of explosive change.Statistical failures possible. Fail safe operationIf device fails, it becomes iron-core reactor and continues to limit current. Requires redundancyIf device fails, circuit is a risk.Redundancy required.
