Key Features: Mnf. Part#: UP3B-39 Designed to protect low voltage applications at the building entrance. UL Primary and Secondary listed with 350mA fuse for voice/fax/modem lines (clamping 39V) Dual Indicator Lights: Protection OK and Ground Connection OK Solid-state Protection: Provides the fastest response to transient voltages (1-5 nanoseconds) by quickly diverting damaging surges to ground and resetting. Single Pair Protection: Scale the protection to the system size. Protect only the lines requiring protection. Streamlined Installation: Eliminate redundant cross-connects by adding protection directly at the 66 Block. Press fit protectors to the the block and attach the ground bar to the protectors.
