UL 2748 1st Edition, September 22, 2017 UL Standard for Safety Arcing Fault Quenching Equipment
More info
Description / Abstract:
These requirements cover equipment intended to quench arcing faults by creating a lower impedance current path, located within a controlled compartment, to cause the arcing fault to transfer to the new current path.
These requirements cover equipment that may either be completely enclosed units or intended to be installed within power distribution equipment.
These requirements cover equipment rated up to 52 kV ac maximum.
This standard does not include the requirements for sensors intended to detect arcing faults, devices intended to trigger the functioning of the arc quenching equipment, or devices that are intended to interrupt arcing fault currents.
This standard does not include all the requirements for integration and testing of arc quenching equipment within equipment it is intended to protect.
