OVR Type 2 surge protective devices - Grounded Wye networks

Description
Wye devices are composed by three MOV poles or three MOV poles plus a spark gap one, depending on
the number of lines the customer wants to protect. The spark gap pole guarantees the lowest voltage 5
protection rating and has to be connected to the Neutral.
OVR T2 devices provide the best protection as they are designed to protect electric installations and
sensitive equipment against indirect surges with ensuring a low protection level (VPR). They are char-
acterized by their capacity to safely discharge current with 8/20 μs wave form.
