E9000* with AFM: Even More Protection
GE’s E9000* Motor Control Center (MCC) with Arc Flash Mitigation (AFM) units is a new offering for customers and specific applications where additional protection of personnel is essential. The AFM units were designed around lowering the electrical shock hazards for motor control centers.
The new AFM unit design includes optional IP20 devices and incidental contact safety barriers in an effort to prevent accidental contact with energized parts during maintenance.
New Level of Arc Flash Mitigation
The E9000 AFM units are designed to reduce the likelihood of exposure to electrical shock and the potential of internal arcing faults from occurring during maintenance. The retractable stab mechanism allows for closed-door racking of the unit, providing added protection to the electrical personnel from the dangers of an arc flash occurrence.
The introduction of a compact NEMA contactor in these AFM units will allow a minimum of IP10 protection with optional IP20 terminal protection for starters using this contactor. Other IP20 protection options are available in starter units including IP20 control power transformer fuses and pilot devices.
Safety. Awareness. Ease of Maintenance.
Safety interlock prevents customers from opening the unit door and racking out the stab when the stab is energized. The visual indicators on the front of the units provide personnel with a clear view of the status of the stab and vertical bus isolation shutter.
