OVRHT3B
OVRHT3B surge protective devices shield sensitive electronic equipment against damaging effects of transients caused by lightning, utility load switching, internal load switching, and more. OVRHT3B is UL 1449 4th Edition listed for Type 1 SPD applications and available on 400 A and below, 50 kA. The individual thermally protected MOVs allows the SPD to take itself offline safely without the need for overcurrent protection. Multiple MOVs per mode eliminate single-point failure. LED lights per phase provide a visual indication of the SPDs operational status. OVRHT3B is ideal for use in sub-distribution and point-of-use applications like UL 508 panelboards.
