UL RECOGNITION
The entire series has
Underwriters Laboratory Recognition
for the classification of protectors (QVGV2) under the UL
standard for safety 497B and File #116110. 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 flammabil-
ity test for the package material, we have been recognized for
much more to be included in their Protector category.
