Underwriters Laboratory Recognition for the classification
of protectors (QVGV2) under the UL standard for safety
497B and File #E 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
