UL RECOGNITION

The

entire

series

has

Underwriters

Laboratory

Recognition for the classification of protectors (QVGV2)

under the UL standard for safety 497B and File #E210057.

Many competitors only have one or two devices recognized

or have recognition in a non-protective category. Some

competitors have no recognition at all. With the UL497B

recognition, our parts successfully passed several tests

including Strike Voltage Breakdown test, Endurance

Conditioning, Temperature test, Dielectric Voltage-Withstand

test, Discharge test and several more.

Whereas, some competitors have only passed a

flammability test for the package material, we have been

recognized for much more to be included in their Protector

category.
