Telecom/Datacom Surge ProtectorsH Series - PBX/KSU Protector with Resettable PTCs & Fuses
The H-Series modules are ultra high speed fused solid state secondary surge protectors for KEY/PABX systems. The units are available in three different clamping voltages. The H-Series is constructed with solid state silicon foldback technology, polyswitch resettable
fuses - PTC's, and failure fuses. These surge protection modules are intended to be used in conjunction with proper primary surge protectors (UL 497). The protective elements switch from the normal high impedance state to a low impedance state upon a detection of a surge, then switch back to
high impedance after the surge has passed. The H-Series single pair modules fit onto a standard M1-50 split block and replace the bridging clips. In addition, these modules require an MGB Ground Rail for each M1-50 block used. SPECIFICATIONS
