OVR T2 AC Surge Protective Devices
OVR T2 Series AC SPDS are Type 4CA UL 1449 5th Ed surge protective devices. They help reduce costly downtime while protecting sensitive electronic equipment against the damaging effects of transients caused by lightning, utility load switching, internal load switching, and more.
SPDs have effective voltage protection ratings, keeping damaging voltage peaks from exceeding the withstand voltages of the protected equipment.
