The Edco H Series modules are ultra high speed fused solid state dual listed
Primary (UL 497) and Secondary (UL 497A) protectors for KEY/PABX systems.
The units are available in two different clamping voltages. The Edco H Series is
constructed with solid state silicon foldback technology, polyswitch resettable
fuses — PTCs — and failure fuses. 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 Edco
H Series single pair modules fit onto a standard Edco MI-50 split block and
replace bridging clips. In addition, these modules require the Edco MGB Ground
Rail for each Edco MI-50 block used.
