Recognition for the classification of protectors (QVGQ2)
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
The entire series has Underwriters Laboratory
