The TPHE surge protective devices shield sensitive electronic equipment against the damaging effects of transients caused by lightning, utility load switching, internal load switching, and more. The TPHE is listed to UL 1449 4th Edition listed for Type 1 and Type 2 SPD applications and are available in 125 to 300 kA per mode surge current ratings, 250 to 600 kA per phase. The TPHE features thermally protected metal oxide varistor (MOV) that ensures maximum performance and safe operation and eliminate the need for additional upstream over current protection. The TPHE standard features include dry contacts for remote monitoring. The TPHE indicating lights inform proper functioning of the device. TPHE was designed for service entrance and mid-level distribution applications.
